## Which one, for what

### Daytona (B)

Good for: Agents that need a choice of machine, including Windows desktops and GPUs, and operators who want least-privilege keys.

Ahead on:
- Reliability, 60 against 25
- Security & auth, 63 against 47
- Payments & pricing, 50 against 20

Also in its favour:
- Runs on your own machine
- Free to start without a card

Watch for: The container class shares the host kernel. Only the VM classes get their own

### Together Code Sandbox (D)

Good for: Teams already buying from Together, and former CodeSandbox SDK users, who want Docker-defined sandboxes with disk and memory snapshots from Python or TypeScript.

Ahead on:
- Agent ergonomics, 70 against 55

Watch for: The SDK and CLI work only for organisations Together has enabled, and the docs say to contact Together for access

## Verdicts

**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.

## Before you call either

### 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
