## Verdicts

**Blaxel Sandboxes.** No compute charge in standby, only $0.20 a GB-month of snapshot storage. 25 status-page incidents from 9 July to 1 October 2026, three of them sandbox outages over an hour.

**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.

## Before you call either

### Blaxel Sandboxes

1. Close WebSocket and terminal connections when done. An open connection keeps the sandbox active and billed
2. Set a TTL or idle expiry on throwaway sandboxes. The default is to keep them
3. Set `forbiddenDomains` or an allow list at creation, with `network.firewall` for tools that ignore proxy settings. Both can only be set when the sandbox is created
4. Retry only on WORKLOAD_UNAVAILABLE. The error reference says other codes won't succeed on retry
5. Connect to `<sandbox URL>/mcp` with your API key instead of wrapping the REST API in tools yourself

### 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
