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.\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### Together Code Sandbox\n\n1. Confirm the organisation is on Together's allowlist before installing. A valid `TOGETHER_API_KEY` alone is not enough\n2. Build a snapshot first with `snapshots.create`. No default image exists, and every sandbox needs `snapshot_id` or `snapshot_alias`\n3. Set `ttl` at creation or call `terminate()`. Nothing stops a sandbox otherwise, and closing the Python client leaves it running\n4. Store the snapshot alias, not the sandbox ID. A terminated sandbox can't restart, and its state lives at `sandbox:\u003cid\u003e`\n5. Exclude `snapshots.create` from retries with `should_retry`, and set `experimental.network_policy` before serving anything private on a port\n\n## Questions\n\n### Which is better for AI agents, Blaxel Sandboxes or Together Code Sandbox?\n\nBlaxel Sandboxes scores 60.7 (C) on agent readiness against Together Code Sandbox's 53.6 (D), and leads in 5 of 7 scored categories. Together Code Sandbox leads on schema \u0026 documentation.\n\n### Do Blaxel Sandboxes and Together Code Sandbox need an API key?\n\nBlaxel Sandboxes takes an API key or an OAuth sign-in. Together Code Sandbox needs an API key.\n\n### Can an agent call Blaxel Sandboxes and Together Code Sandbox without installing anything?\n\nYes. Blaxel Sandboxes has a hosted endpoint at https://api.blaxel.ai/v0 and Together Code Sandbox at https://api.bartender.codesandbox.io.\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-together-code-sandbox.json, and with the fewest tokens: https://www.anchorterminal.com/compare/blaxel-sandboxes-vs-together-code-sandbox.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"blaxel-sandboxes\", \"b\": \"together-code-sandbox\"}`.
