No REST API, and the JavaScript and Go SDKs are beta.\n\n**Sandbox0.** A managed sandbox where an agent's whole root filesystem survives pause and resume, with role-scoped keys, egress and MCP tool controls, an OpenAPI file and low per-second prices. 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### Modal Sandboxes\n\n1. Pass `timeout=` when you create a sandbox. The default lifetime is 5 minutes\n2. Set `block_network=True` or an `outbound_cidr_allowlist` for untrusted code\n3. Give a sandbox a `name` so a retried create raises `AlreadyExistsError` instead of starting a second one\n4. Snapshot the filesystem before the 24-hour limit and start a fresh sandbox from it\n5. Catch `ResourceExhaustedError` from `Sandbox.create()` on SDK 1.6.0 and later, since create now waits until scheduled\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, Modal Sandboxes or Sandbox0?\n\nModal Sandboxes scores 65.9 (B) on agent readiness against Sandbox0's 55.1 (C), and leads in 5 of 7 scored categories.
