How We Compared E2B and Daytona
E2B and Daytona both provision isolated Linux environments for agent-generated code, but they diverge sharply on the dimensions that matter for security-sensitive workloads: what state persists across sessions, who owns the audit trail, how operators constrain and observe running sandboxes, and what enterprise deployment options exist. The meaningful comparison is in isolation model, persistence semantics, audit log fidelity, and multi-tenant access controls.
| Criterion | E2B | Daytona |
|---|---|---|
| Isolation model | Managed secure Linux VM per sandbox | Dedicated kernel, filesystem, network stack per sandbox |
| Persistence on pause/stop | Filesystem and memory state preserved (pause) | Filesystem preserved; memory cleared (stop) |
| Snapshot semantics | Point-in-time capture of filesystem + memory; one-to-many spawn | Docker/OCI-compatible image templates; reproducible environments |
| Audit logs | Resource metrics (CPU/mem/disk) + BYOC runtime logs | First-class audit log feature: lifecycle, user access, system changes |
| Multi-tenant controls | Template-based isolation; BYOC VPC option | Audit logs + webhooks + volumes; SDK/API/CLI/Dashboard management |
| Max sandbox lifetime | 24 h (Pro), 1 h (Hobby) | Not time-bounded by a fixed tier cap in published docs |
| Enterprise deployment | BYOC VPC: templates, snapshots, logs in customer VPC | Self-host option; webhook-driven integrations |
| Terminal / file access | SSH (remote sessions, SCP/SFTP), terminal | SDK, CLI, API, Dashboard |
| MCP gateway support | Yes | Not documented |
E2B's model centers on fast, managed provisioning with well-defined lifecycle APIs. Daytona's model centers on stateful workspaces with broader observability primitives. Neither is a strict superset of the other.
At-a-Glance Comparison: Security, Persistence, and Operations
For untrusted agent execution, both platforms reduce host-escape risk through kernel-level isolation. The operative difference for buyers is what survives a session boundary and who can see it afterward.
| Feature | E2B | Daytona |
|---|---|---|
| Sandbox lifecycle API | Create, pause, resume, snapshot | Create, start, stop, snapshot (Docker/OCI) |
| Filesystem state on stop | Preserved (pause) | Preserved (stop) |
| Memory state on stop | Preserved (pause) | Cleared |
| Shared storage across sandboxes | Volumes | FUSE-based volumes backed by S3-compatible store |
| Metrics telemetry | CPU/mem/disk, sampled every 5 seconds | Not detailed in public docs |
| Audit log feature | No dedicated audit log; metrics + BYOC runtime logs | Dedicated audit logs: lifecycle, user access, system changes |
| Webhooks | Not documented as a first-class feature | Real-time webhook integration |
| Enterprise / BYOC | BYOC VPC for templates, snapshots, runtime logs | Self-host, API-driven |
| SSH access | Yes — remote terminal, SCP/SFTP | Not documented separately |
Daytona's docs confirm that "stopped sandboxes maintain filesystem persistence while their memory state is cleared." E2B metrics docs show metrics are collected every 5 seconds and return timestamped CPU, memory, and disk usage. Daytona volumes are FUSE-based mounts backed by an S3-compatible store, enabling shared file access across multiple sandboxes — a capability relevant for multi-agent pipelines. E2B SSH access supports remote terminal sessions and SCP/SFTP file transfers.
Isolation model and attack surface
Both platforms provide kernel-level isolation that prevents a compromised sandbox from directly accessing the host or adjacent tenants. E2B describes its sandboxes as "secure isolated sandboxes in the cloud" for AI-generated code. Daytona's GitHub README specifies "complete isolation, a dedicated kernel, filesystem, network stack, and allocated vCPU, RAM, and disk" per sandbox.
The practical difference in attack surface comes from management plane exposure, not the sandbox VM boundary itself. E2B's managed service abstracts host and control-plane detail, which reduces operator configuration error but also reduces operator visibility into the infrastructure layer. Daytona's broader API surface — SDK, CLI, API, Dashboard — creates more integration points that require access policy review.
Pro Tip: Kernel isolation eliminates host-escape and neighbor-tenant exposure. It does NOT prevent a malicious agent from deleting files it has write access to, exfiltrating data over the sandbox's internet connection, or calling external APIs with credentials it finds in the environment. Your threat model for agent sandboxes must account for what the agent can legitimately do, not just what it cannot escape to.
Persistence, snapshots, and session continuity
E2B and Daytona use different persistence primitives with different security implications.
| Primitive | E2B | Daytona |
|---|---|---|
| Pause/stop behavior | Filesystem + memory saved | Filesystem saved; memory cleared |
| Resume from exact state | Yes (pause/resume) | No — memory state does not survive stop |
| Snapshot creation | Point-in-time capture of running sandbox (filesystem + memory) | Docker/OCI image template |
| Snapshot reuse | One snapshot → many new sandboxes | Reproducible environment from image |
| Shared storage | Volumes | FUSE volumes (S3-compatible backend) |
| Disk resize on running sandbox | Not documented | Requires stopped sandbox; CPU/mem can increase on running |
E2B's snapshot docs state: "Snapshots let you create a persistent point-in-time capture of a running sandbox, including both its filesystem and memory state." This full-state capture enables spawning N identical sandboxes from a single snapshot — useful for horizontal scaling of agent tasks and for reproducing a security incident to a known-good state.
Daytona's stopped sandboxes, per its sandbox docs, preserve filesystem state only. Daytona snapshots are Docker/OCI-compatible images, which gives reproducible base environments but does not capture in-flight memory state. For long-lived agent workflows where an agent accumulates context across sessions, Daytona's approach means that context must be reconstructed from filesystem artifacts rather than memory resume.
The security implication: filesystem-persistent sandboxes accumulate state across stop/start cycles. Operators using Daytona must define explicit data retention and deletion policies for stopped sandbox filesystems, or an agent's prior session artifacts will be present in the next session.
Observability, telemetry, and sandbox audit logs
This is the sharpest differentiator for regulated buyers. Daytona ships a dedicated audit log feature; E2B's observability is primarily resource telemetry plus BYOC runtime logs.
| Observability dimension | E2B | Daytona |
|---|---|---|
| Dedicated audit logs | No | Yes — lifecycle events, user access, system changes |
| Resource metrics | CPU/mem/disk, 5-second samples, timestamped | Not detailed in public docs |
| Runtime logs | Available in BYOC VPC | Part of audit log feature |
| Webhooks for live events | Not documented as first-class | Real-time event delivery for automation and monitoring |
| Metadata | Sandbox metadata available | User + system activity records |
| Incident reconstruction support | Correlate resource spikes to timeline | Lifecycle events + access trail |
Daytona's audit log documentation states: "Daytona audit logs provide a detailed record of user and system activity across your organization" and cover "sandbox lifecycle events, user access, system changes, and more." This is a first-class feature designed for compliance and incident review — not a secondary metrics endpoint.
E2B metrics docs state the endpoint returns "an array of timestamped metrics containing CPU, memory and disk usage information" sampled every 5 seconds. This is resource telemetry, not an action audit trail. For incident reconstruction — determining what an agent wrote, which files it deleted, or which external calls it made — E2B's metrics alone are insufficient. Under the BYOC deployment model, runtime logs are stored in the customer's VPC, which brings them under customer control, but the docs are explicit that "anonymized system metrics such as cluster memory and cpu are sent to the E2B Cloud for observability and cluster management purposes."
Regulated buyers who need to answer "what did the agent do in this session and who authorized it?" will find Daytona's audit log feature closer to a compliance primitive than E2B's current telemetry model.
E2B for security-sensitive agent workflows
E2B's strength for security-sensitive workloads is the combination of a managed, fast-provisioning lifecycle with a BYOC VPC option that keeps sensitive artifacts under customer control. The E2B BYOC docs confirm: "Sandbox templates, snapshots, and runtime logs are stored within the customer's BYOC VPC." That means the artifacts most relevant to a security review — what the sandbox was configured to run, what state it captured, and its runtime logs — can remain inside your own network boundary.
Pro Tip: E2B's template and snapshot system is operationally useful for security review: you can define a locked-down base image as a template, snapshot a known-good state before an agent run, and restore from that snapshot after. Combined with BYOC VPC placement, this gives a defensible chain of custody for the sandbox's provenance without requiring full self-hosted infrastructure.
The MCP gateway support and SSH access — including SCP/SFTP file transfers — make E2B well-suited for agent workflows that need programmatic file exchange and tool integration. Internet access is configurable per sandbox.
Where E2B is strongest
| Feature | Detail |
|---|---|
| Managed provisioning | On-demand Linux VM; fast lifecycle with pause/resume/snapshot APIs |
| Snapshot fidelity | Filesystem + memory state captured; one-to-many spawn |
| SSH access | E2B SSH access enables remote terminal sessions and SCP/SFTP file transfers |
| Resource telemetry | E2B metrics docs show CPU/mem/disk at 5-second resolution, timestamped |
| BYOC VPC | E2B BYOC docs keep templates, snapshots, runtime logs in customer VPC |
| MCP gateway | Documented support for Model Context Protocol integrations |
| Internet access | Configurable per sandbox |
| Terminal | Direct terminal access per sandbox |
E2B's pause/resume preserves both filesystem and memory state, which is the strongest continuity primitive either platform offers. For agent workflows where in-flight memory context is operationally significant (e.g., an agent that has loaded a large dataset or built an in-memory index), E2B's pause/resume is the only option on this comparison that keeps that state intact.
Where E2B may be limiting
The managed service model that makes E2B fast to adopt creates operator visibility constraints that matter during incident response. When a sandbox behaves abnormally, the host-level and control-plane details are abstracted by the service. Operators cannot directly inspect hypervisor state, network captures at the host level, or infrastructure logs below the sandbox API surface unless they have deployed under BYOC VPC.
Lifetime constraints bind real workloads: E2B's SDK reference documents a maximum sandbox alive time of 24 hours for Pro users and 1 hour for Hobby users. Long-running agent jobs must either complete within these bounds or implement external checkpointing logic.
Watch Out: Under the default (non-BYOC) E2B deployment, compliance teams cannot assume all sensitive artifacts stay within their network boundary. The BYOC docs explicitly note that "anonymized system metrics such as cluster memory and cpu are sent to the E2B Cloud for observability and cluster management purposes" even when templates and logs are customer-VPC-resident. Any compliance review must map which artifact categories flow where before approving regulated workloads. Managed infrastructure that simplifies operations can make forensic reconstruction harder when an incident requires correlating low-level host events.
Daytona for long-lived and multi-session agent workspaces
Daytona fits workloads where agent sessions are not ephemeral — where filesystem state accumulates meaningfully across multiple runs, multiple agents share data through volumes, and the operator needs a structured audit trail. Daytona sandboxes can be created and managed through dashboard, SDKs, CLI, or API, and support specifying resources, regions, environment variables, and volumes at creation time per the Daytona sandbox docs.
| Lifecycle characteristic | Daytona behavior |
|---|---|
| Stop/start continuity | Filesystem persists; memory clears |
| Shared cross-sandbox storage | FUSE volumes, S3-compatible backend |
| Snapshot type | Docker/OCI-compatible image templates |
| Multi-session continuity | Filesystem-based; agents reconstruct from disk |
| Management interfaces | SDK, CLI, API, Dashboard |
| Audit trail | Dedicated audit logs with lifecycle, access, system events |
| Real-time event integration | Webhooks |
Daytona volumes, per the volume docs, are "FUSE-based mounts that provide shared file access across Daytona Sandboxes" stored in an S3-compatible object store. For multi-agent pipelines — where one agent produces artifacts consumed by another — this is the operative primitive. Cross-sandbox shared state without manual file transfer is a meaningful operational advantage for complex agent topologies.
Where Daytona is strongest
| Strength | Detail |
|---|---|
| Dedicated audit logs | Lifecycle events, user access, system changes — org-wide |
| Webhook integration | Real-time event delivery for monitoring and automation |
| Filesystem persistence | Survives stop/start without operator intervention |
| Shared volumes | Cross-sandbox FUSE mounts, S3-compatible |
| Snapshot model | Docker/OCI compatible; reproducible base environments |
| Isolation depth | Daytona README states complete isolation, a dedicated kernel, filesystem, network stack, and allocated compute resources |
| Management flexibility | Daytona docs show sandboxes can be managed via SDK, CLI, API, Dashboard and can specify resources, regions, environment variables, and volumes |
Daytona's GitHub README describes it as a "secure and elastic infrastructure runtime for AI-generated code execution and agent workflows." The dedicated audit log feature — tracking lifecycle events, user access, and system changes — is the feature most absent in E2B's current public documentation, and it is the primary reason a regulated buyer would favor Daytona for workloads that require demonstrable access review.
Where Daytona may be limiting
The breadth of Daytona's API surface is also its operational complexity. Audit logs, webhooks, volumes, snapshots, and multiple management interfaces each represent a policy surface that requires review, access control, and retention configuration. Teams that have not built these processes will not get the benefit of the observability features — they will get compliance debt.
Watch Out: Daytona's filesystem persistence means stopped sandboxes accumulate data indefinitely unless deletion policies are explicitly enforced. For regulated workloads, a stopped sandbox that retains PII or secrets from a prior agent session is a data-retention liability. The broader API surface — webhooks, volumes, audit log access — also expands the IAM review scope: each integration point is a potential unauthorized access vector if access controls are not maintained. Daytona's controls give you more to configure correctly, not fewer things to get wrong.
Daytona's snapshot model is based on Docker/OCI images rather than full in-memory state capture. Agents that rely on in-memory state across a stop event will lose that context and must reconstruct it from filesystem artifacts.
Security and compliance decision matrix
The primary selection axis for regulated workloads is: where do sensitive artifacts live, and what is the fidelity of the audit trail?
| Criterion | E2B | Daytona |
|---|---|---|
| Untrusted code execution | Managed isolation; lifecycle APIs reduce configuration error | Complete isolation with dedicated kernel; broader operator control |
| Regulated workloads | BYOC VPC keeps templates, snapshots, logs in customer network | Audit logs cover lifecycle, access, changes; customer-managed retention |
| Audit log fidelity | Resource metrics (CPU/mem/disk) + BYOC runtime logs | Dedicated audit log: lifecycle events, user access, system changes |
| Memory persistence across sessions | Full (pause/resume) | None (stop clears memory) |
| Filesystem persistence across sessions | Full (pause/resume) | Full (stop preserves filesystem) |
| Operator control plane | Managed service; host-level details abstracted | SDK/API/CLI/Dashboard; audit + webhook integration |
| Sandbox audit logs for incident review | Runtime logs in BYOC VPC; metrics for timeline correlation | First-class feature with org-wide activity records |
Choose E2B when the priority is managed isolation
E2B is the right choice when your primary risk is operator misconfiguration and you need fast, reproducible sandbox provisioning without managing infrastructure. The template system — with BYOC VPC storage of templates, snapshots, and runtime logs — gives a defensible chain of custody while keeping the operational surface minimal. Teams shipping agent features at pace, who need lifecycle APIs rather than a self-managed control plane, and whose compliance requirements can be satisfied by BYOC VPC artifact placement, should default to E2B.
| Priority | E2B fit |
|---|---|
| Fast, managed provisioning | Strong — on-demand Linux VMs with lifecycle API |
| Reproducible base environments | Strong — templates and snapshots |
| Full in-memory continuity across sessions | Strong — pause/resume preserves memory state |
| BYOC artifact control | Strong — templates, snapshots, runtime logs in customer VPC |
| Dedicated audit trail | Weak — resource metrics, not action audit logs |
Choose Daytona when the priority is stateful agent work
Daytona is the right choice when agents run across multiple sessions, share data through volumes, and the compliance team needs an audit log that covers lifecycle events and user access rather than just resource metrics. The filesystem persistence across stop/start cycles, combined with shared FUSE volumes and a dedicated audit log feature, makes Daytona the stronger fit for multi-agent pipelines and workloads where you need to demonstrate access review.
| Priority | Daytona fit |
|---|---|
| Multi-session filesystem continuity | Strong — stop preserves filesystem |
| Cross-sandbox shared state | Strong — FUSE volumes, S3-compatible |
| Dedicated org-wide audit logs | Strong — lifecycle, access, system changes |
| Real-time event integration | Strong — webhooks |
| Full in-memory continuity across sessions | Weak — stop clears memory state |
| Managed infrastructure (low ops burden) | Weaker than E2B — broader surface to configure |
Red-team scenarios that stress both platforms
Isolation prevents sandbox escape. It does not prevent an agent from acting badly within its granted permissions. The following scenarios expose where each platform's controls actually matter.
| Scenario | E2B exposure | Daytona exposure | Mitigating control |
|---|---|---|---|
| Agent deletes files it has write access to | Pause/resume snapshot creates recoverable prior state; BYOC logs track timing via metrics | Filesystem persists on stop — deletion survives; audit logs record system changes | Snapshots before agent run (E2B); audit log review (Daytona) |
| Agent sends email via SMTP in sandbox | Internet access is configurable; sandbox isolation does not block outbound network by default | Same; network policy is operator responsibility | Network egress restriction outside sandbox isolation |
| Agent exfiltrates credentials found in environment | BYOC runtime logs capture activity; metrics flag anomalous resource use | Audit logs track user access and system changes; webhooks can alert in real time | Secrets management outside sandbox; audit log monitoring |
| Cross-session persistence abuse | Filesystem and memory state persist on pause — prior session artifacts present on resume | Filesystem persists on stop; memory clears — prior session filesystem present on next start | Daytona audit logs cover system changes; E2B operators must track pause state lifecycle |
| Agent spawns N sandboxes from compromised snapshot | E2B's one-to-many snapshot spawn can propagate a compromised state at scale | Daytona's OCI image snapshots propagate to all sandboxes built from that image | Snapshot integrity verification before spawn |
| Money movement via API call in sandbox | Outside sandbox scope — depends on credentials present in environment | Same | Credential isolation, not sandbox isolation |
Cross-session persistence abuse is the scenario most commonly overlooked. On both platforms, filesystem state surviving a session boundary means that an agent operating in a later session inherits artifacts from the prior one. On E2B, pause/resume explicitly saves both filesystem and memory state. On Daytona, stopped sandboxes maintain filesystem persistence — meaning the prior session's working directory, cached credentials, and intermediary outputs are present when the next session starts. Daytona's audit logs covering system changes are the primary mechanism for detecting what was left behind; E2B's 5-second metrics sampling creates a resource-use timeline but does not describe file-level actions.
Operational questions buyers ask before rollout
Both platforms expose terminal and file operations, but through different mechanisms, and their webhook and metadata story diverges enough to affect incident response processes.
| Operational question | E2B | Daytona |
|---|---|---|
| Remote terminal access | E2B SSH access enables remote terminal sessions and SCP/SFTP file transfers | SDK/API/CLI commands; not documented as SSH specifically |
| File operations | SCP/SFTP via SSH; filesystem API | FUSE volumes; SDK/API filesystem operations |
| Remote execution | Sandbox API + terminal; GitHub Actions integration documented | SDK, CLI, API, Dashboard |
| Webhook / event integration | Not documented as first-class | First-class webhooks for real-time event delivery |
| Audit-friendly metadata | BYOC runtime logs in customer VPC; metrics timestamped | Daytona audit logs for org-wide activity tracking |
| Rollback mechanism | Restore from snapshot (filesystem + memory) | Restart from stopped state (filesystem only); rebuild from OCI snapshot |
| Runtime logs | In BYOC VPC | Part of audit log feature |
E2B's SSH access enables remote terminal sessions, SCP/SFTP file transfers, and integration with tools that expect SSH connectivity — which covers a broad class of CI/CD and agent orchestration tooling. Daytona's multiple management interfaces — SDK/CLI/API/Dashboard — offer more ways to interact with the control plane but do not document SSH as a distinct access path in the same way.
Daytona webhooks "connect your applications to Daytona events in real-time" for automation, monitoring, and integrations. This means security tooling can subscribe to lifecycle events and alert on anomalous patterns without polling. The absence of a documented equivalent in E2B's public docs means E2B operators building real-time alerting must construct it from the metrics API or external monitoring on the BYOC VPC.
How sandbox audit logs support incident review
For incident reconstruction — answering "what did the agent do, when, and who authorized it?" — the two platforms offer fundamentally different primitives.
| Log type | E2B | Daytona |
|---|---|---|
| Action audit trail | Not documented; runtime logs in BYOC VPC | Dedicated audit logs: lifecycle events, user access, system changes |
| Resource telemetry | CPU/mem/disk, 5-second samples, timestamped | Not detailed in public docs |
| Lifecycle event log | Lifecycle managed via API; no explicit lifecycle event log in public docs | Lifecycle events covered in audit logs |
| Real-time alerting | Not documented as first-class | Webhook integration |
| Log storage location | BYOC VPC (runtime logs); E2B Cloud (anonymized metrics) | Customer-managed (retention and storage policies require operator configuration) |
Daytona's audit log documentation states the feature provides "a detailed record of user and system activity across your organization" and covers "sandbox lifecycle events, user access, system changes, and more." This is the artifact an incident responder needs to reconstruct a timeline: when was the sandbox created, who accessed it, and what changed.
E2B's metrics endpoint delivers "timestamped metrics containing CPU, memory and disk usage information" — useful for correlating an anomaly to a time window, but not for determining what action caused the anomaly. Under BYOC, runtime logs in the customer VPC provide the closest equivalent to an action log, but the scope and retention of those runtime logs requires validation against the BYOC docs before treating them as a compliance substitute for structured audit logs.
What to verify in a regulated deployment
Before approving either platform for regulated workloads, compliance leads must verify claims against actual vendor documentation rather than marketing summaries.
Watch Out: The following items require explicit verification before production rollout in regulated environments:
- BYOC VPC boundary (E2B): Confirm which artifact categories flow to E2B Cloud versus remaining in your VPC. The BYOC docs confirm anonymized metrics leave the VPC; verify whether any other telemetry or metadata does.
- Retention windows: Neither vendor publishes a single canonical retention guarantee for all log types. Operators must configure and verify retention for runtime logs, audit logs, and metrics separately.
- Identity provider integration: Verify that audit log access and sandbox management interfaces integrate with your IdP for least-privilege review.
- Sandbox audit logs storage and access controls: For Daytona, the audit log feature needs explicit access restriction so that only authorized reviewers can query it.
- Snapshot and volume deletion policies: Stopped Daytona sandboxes and their volumes retain data until explicitly deleted; E2B snapshots persist until removed. Neither platform auto-expires sensitive artifacts by default in current documentation.
Which sandbox should you choose?
| Use case | Recommended platform | Reason |
|---|---|---|
| Security-sensitive managed agent execution | E2B | Fast lifecycle API, pause/resume with full state, BYOC VPC for artifact control, SSH access |
| Long-lived multi-session agent workspaces | Daytona | Filesystem persistence across stop/start, shared FUSE volumes, dedicated audit logs |
| Regulated environments requiring action audit trails | Daytona | First-class audit log feature covering lifecycle, access, and system changes |
| Rapid deployment without infrastructure management | E2B | Managed service; minimal configuration surface |
| Multi-agent pipelines with shared state | Daytona | Cross-sandbox FUSE volumes backed by S3-compatible store |
| Workloads needing full in-memory session continuity | E2B | Pause/resume preserves both filesystem and memory state |
| Real-time event-driven monitoring | Daytona | Webhook integration for live event delivery |
| BYOC artifact control with managed infra | E2B | Templates, snapshots, runtime logs in customer VPC under managed service |
E2B is the default choice when your security model prioritizes isolation with minimal operator surface, fast provisioning, and full-state pause/resume. Daytona is the default choice when your security model requires a structured audit trail, filesystem continuity across sessions, and multi-agent shared storage. For regulated environments where compliance teams must demonstrate access review, Daytona's dedicated audit log feature is the deciding feature — E2B's current public documentation does not offer a direct equivalent. Teams that need both managed provisioning simplicity and a structured audit trail should evaluate E2B's BYOC deployment alongside Daytona's full feature set against their specific compliance control requirements.
FAQ
What is the difference between E2B and Daytona?
E2B provides managed, fast-provisioning Linux sandboxes with pause/resume full-state persistence, BYOC VPC artifact control, and lifecycle APIs. Daytona provides isolated sandboxes with filesystem persistence across stop/start, shared cross-sandbox FUSE volumes, and a dedicated audit log feature covering lifecycle events, user access, and system changes. The core difference is that E2B optimizes for managed simplicity and full in-memory continuity, while Daytona optimizes for stateful multi-session workflows with structured observability.
Is E2B secure?
E2B sandboxes provide kernel-level isolation from the host and adjacent tenants. The GitHub README describes "secure isolated sandboxes in the cloud." Under BYOC VPC deployment, sensitive artifacts — templates, snapshots, runtime logs — stay in the customer's network. The limitation is that E2B does not document a dedicated action audit log feature; observability is resource-metric-based. Isolation does not prevent an agent from taking damaging actions within its granted scope.
Does Daytona support persistent sandboxes?
| State transition | Filesystem state | Memory state |
|---|---|---|
| E2B pause → resume | Preserved | Preserved |
| Daytona stop → start | Preserved | Cleared |
Yes, but with a specific definition: Daytona's stopped sandboxes maintain filesystem persistence while memory state is cleared. Agents that need filesystem continuity across sessions get it on Daytona. Agents that need in-memory state continuity across sessions do not — E2B's pause/resume is the only option on this comparison that delivers that.
Which sandbox is better for AI agents?
Neither platform is unconditionally better. E2B is better when isolation simplicity, fast lifecycle APIs, and in-memory continuity are the priorities. Daytona is better when multi-session filesystem continuity, shared cross-sandbox storage, or a compliance-grade audit trail is required.
How do sandbox audit logs work?
Daytona's dedicated audit log feature records sandbox lifecycle events, user access, and system changes at the organizational level. These logs support incident reconstruction and access review. E2B's equivalent is a combination of resource metrics (CPU/mem/disk, 5-second samples) and — under BYOC deployment — runtime logs stored in the customer's VPC. E2B's metrics are not action audit logs; they establish a resource-use timeline rather than an access-and-action record.
