The service is still in beta, sandboxes need the $20 Pro plan, lifetime is capped at 30 minutes, and no sandbox operation appears in the published OpenAPI document.\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### Deno Sandbox\n\n1. Set `DENO_DEPLOY_TOKEN` to an organisation token (prefix `ddo_`) from Settings in console.deno.com. The organisation must be on Pro or above\n2. Pass `allowNet` on every `Sandbox.create()`. The Security page says outbound access is unrestricted when it is omitted\n3. Pass credentials through `secrets` with a `hosts` list, not `env`, so code in the VM sees only a placeholder\n4. The default timeout ends the VM when the client disconnects. Pass a duration such as `\"10m\"` and reconnect with `Sandbox.connect({ id })`, up to 30 minutes\n5. Create volumes in `ord` and start the sandbox in `ord`. A volume mounts only in its own region\n6. `exposeHttp` URLs are public with no authentication. Treat the random subdomain as a secret\n\n## Questions\n\n### Which is better for AI agents, Blaxel Sandboxes or Deno Sandbox?\n\nBlaxel Sandboxes scores 60.7 (C) on agent readiness against Deno Sandbox's 50.3 (D), and leads in 6 of 7 scored categories. Deno Sandbox leads on reliability.\n\n### Do Blaxel Sandboxes and Deno Sandbox need an API key?\n\nBlaxel Sandboxes takes an API key or an OAuth sign-in. Deno Sandbox needs an API key.\n\n### Can an agent call Blaxel Sandboxes and Deno Sandbox without installing anything?\n\nBlaxel Sandboxes has a hosted endpoint at https://api.blaxel.ai/v0. No hosted endpoint is listed for Deno Sandbox.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-deno-sandbox.json, and with the fewest tokens: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-deno-sandbox.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"blaxel-sandboxes\", \"b\": \"deno-sandbox\"}`.
