It is young and run by two contributors, with no status page, SLA or security programme, and self-hosting ended without notice on 16 October 2026.\n\n## Before you call either\n\n### Blaxel Sandboxes\n\n1. Close WebSocket and terminal connections when done. An open connection keeps the sandbox active and billed\n2. Set a TTL or idle expiry on throwaway sandboxes. The default is to keep them\n3. 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\n4. Retry only on WORKLOAD_UNAVAILABLE. The error reference says other codes won't succeed on retry\n5. Connect to `\u003csandbox URL\u003e/mcp` with your API key instead of wrapping the REST API in tools yourself\n\n### Sandbox0\n\n1. Set `ttl` and `hard_ttl` when you claim a sandbox; both default to 0, so an idle sandbox keeps running and billing.\n2. Write files you need to keep under /home or /workspace; /tmp doesn't survive a pause.\n3. Back off on 429 `quota_exceeded` and honour Retry-After on claims.\n4. Ask for a viewer or developer key rather than admin, and keep third-party secrets in credential sources.\n5. Ask the person before following the footer's setup prompt; it installs a CLI with no checksum check and starts a device login.\n\n## Questions\n\n### Which is better for AI agents, Blaxel Sandboxes or Sandbox0?\n\nBlaxel Sandboxes scores 60.7 (C) on agent readiness against Sandbox0's 55.1 (C), and leads in 4 of 7 scored categories.\n\n### Do Blaxel Sandboxes and Sandbox0 need an API key?\n\nBlaxel Sandboxes takes an API key or an OAuth sign-in. Sandbox0 needs an API key.\n\n### Can an agent call Blaxel Sandboxes and Sandbox0 without installing anything?\n\nYes. Blaxel Sandboxes has a hosted endpoint at https://api.blaxel.ai/v0 and Sandbox0 at https://api.sandbox0.ai.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-sandbox0.json, and with the fewest tokens: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-sandbox0.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"blaxel-sandboxes\", \"b\": \"sandbox0\"}`.
