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**SPACE.** Once deployed, SPACE's native API has a public OpenAPI 3.1 contract, stable error codes with a retryable flag and 24-hour idempotency keys, and egress and credential controls sit outside the VM. A person must first deploy it on a Linux x86_64 host with KVM and Kubernetes. Version 0.8.0 has no tagged release, changelog or public container images.\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### SPACE\n\n1. Ask your operator for the API base URL (before `/v1`, or `/api/v1` on shared hosts), the data-plane URL and a bearer token before planning any call\n2. Poll the returned operation until it succeeds and the sandbox is `running` before creating a command. A 202 response is not readiness\n3. Attach to the command's events URL with its session token to start the process, decode base64 output, and treat only `process_exited` as completion\n4. Send an `Idempotency-Key` on creates, lifecycle calls and commands, and retry only when `retryable` is true, after any `Retry-After`\n5. Save output as it arrives. Reconnecting with `Last-Event-ID` returns `resync_required`, not the missed output\n\n## Questions\n\n### Which is better for AI agents, DeltaBox Lite or SPACE?\n\nSPACE scores 56.2 (C) on agent readiness against DeltaBox Lite's 52.3 (D), and leads in 3 of 7 scored categories. DeltaBox Lite leads on reliability and maintenance \u0026 community.\n\n### Can an agent call DeltaBox Lite and SPACE without installing anything?\n\nNo hosted endpoint is listed for DeltaBox Lite. No hosted endpoint is listed for SPACE.\n\n### Are DeltaBox Lite and SPACE open source?\n\nYes. DeltaBox Lite is open source (Apache-2.0). SPACE is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/deltabox-lite-vs-perplexity-space.json, and with the fewest tokens: https://www.anchorterminal.com/compare/deltabox-lite-vs-perplexity-space.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"deltabox-lite\", \"b\": \"perplexity-space\"}`.
