Daytona vs Together Code Sandbox

Daytona

API keys with per-action scopes, so an agent can create sandboxes without being able to delete them. The container class shares the host kernel. Only the VM classes get their own.

Together Code Sandbox

Two public OpenAPI documents, MIT clients for Python and TypeScript, cursor pagination and built-in retries make the surface easy for an agent to drive. Access is the limit. Together enables the SDK per organisation on request, publishes no rate limits or SLA, and neither status page names the sandbox service.

Daytona

1. Pick a Linux VM class for untrusted code or when memory must survive a pause. Container sandboxes stop and archive instead
2. Set autoStopInterval yourself. The 15-minute idle default can stop a sandbox while the agent is still thinking
3. Give the agent a key without delete:sandboxes if it shouldn't destroy work
4. Read Retry-After-{throttler} on a 429 before retrying sandbox creation
5. Check the organisation's tier before relying on outbound calls from inside the sandbox

Together Code Sandbox

1. Confirm the organisation is on Together's allowlist before installing. A valid TOGETHER_API_KEY alone is not enough
2. Build a snapshot first with snapshots.create. No default image exists, and every sandbox needs snapshot_id or snapshot_alias
3. Set ttl at creation or call terminate(). Nothing stops a sandbox otherwise, and closing the Python client leaves it running
4. Store the snapshot alias, not the sandbox ID. A terminated sandbox can't restart, and its state lives at sandbox:<id>
5. Exclude snapshots.create from retries with should_retry, and set experimental.network_policy before serving anything private on a port
