No terms of service, product privacy policy, request rate limit or incident history was found, and the only SDK is TypeScript.\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### Freestyle\n\n1. Send a `firewall` object on every `POST /v5/vms`. It is required, and a VM with no rules has no outbound internet\n2. Ask the owner to run `freestyle login` in a browser once, then mint a key with `freestyle tokens create --output json`\n3. Do not retry an exec that answers 409 `VM_NON_RESPONSIVE`. The command may already have run\n4. Keep `exec-await` under its 300,000 ms cap and use a PTY session or `x-freestyle-background-after-secs` for longer work\n5. Call the `/v5` paths. The unversioned duplicates in the OpenAPI file are marked deprecated\n\n## Questions\n\n### Which is better for AI agents, Blaxel Sandboxes or Freestyle?\n\nBlaxel Sandboxes scores 60.7 (C) on agent readiness against Freestyle's 58.5 (C), and leads in 4 of 7 scored categories. Freestyle leads on reliability, schema \u0026 documentation and payments \u0026 pricing.\n\n### Do Blaxel Sandboxes and Freestyle need an API key?\n\nBlaxel Sandboxes takes an API key or an OAuth sign-in. Freestyle needs an API key.\n\n### Can an agent call Blaxel Sandboxes and Freestyle without installing anything?\n\nYes. Blaxel Sandboxes has a hosted endpoint at https://api.blaxel.ai/v0 and Freestyle at https://api.freestyle.sh/v5.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-freestyle.json, and with the fewest tokens: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-freestyle.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"blaxel-sandboxes\", \"b\": \"freestyle\"}`.
