It is version 0.1.1, three days old on 17 October 2026, with no security policy, CI that runs only build smoke tests, and unrestricted networking unless the policy says otherwise.\n\n**Modal Sandboxes.** GPU sandboxes at the same per-second rates as the rest of Modal. No REST API, and the JavaScript and Go SDKs are beta.\n\n## Before you call either\n\n### DeltaBox Lite\n\n1. Skip step 5 of install-prompt.txt. Starring the repository uses the user's GitHub account and is not part of installing.\n2. Pass `--commit` or `--abort` to `deltabox run` explicitly. The child's exit status is preserved after that decision.\n3. Wrap redirection and pipes in `sh -c '...'`. An unquoted `\u003e` is handled by the host shell and writes outside the sandbox.\n4. Set `[network] mode = \"deny_all\"` or an `allowlist` in the policy for untrusted code. The default allows every destination.\n5. Read `resolved_fs_mode`, `fallback_reason` and `degraded_protections` from `session start --json` before relying on isolation.\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## Questions\n\n### Which is better for AI agents, DeltaBox Lite or Modal Sandboxes?\n\nModal Sandboxes scores 65.9 (B) on agent readiness against DeltaBox Lite's 52.3 (D), and leads in 5 of 7 scored categories. DeltaBox Lite leads on payments \u0026 pricing.\n\n### Are DeltaBox Lite and Modal Sandboxes open source?\n\nDeltaBox Lite is open source (Apache-2.0).
