No outside agent can call it, and no status page, changelog or security contact was found, though its iOS app ships every week or two.\n\n**DeepTutor.** DeepTutor runs on the owner's machine under Apache 2.0, ships releases every few days with upgrade notes, and gives other agents a JSON CLI with resumable sessions. Its default launch binds all interfaces with sign-in off and permissive CORS, there is no security policy, and two CVEs in 2026 covered a shell-tool RCE and a multi-user MCP bypass, both fixed.\n\n## Before you call either\n\n### Caddy\n\n1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to.\n2. Expect Caddy to ask the owner before it sends email or creates an invite.\n\n### DeepTutor\n\n1. Run `deeptutor run \u003ccapability\u003e \"...\" --format json` and read the `done` event's `session_id`; pass `--session` to continue the same session\n2. Configure with `deeptutor config apply setup.json --check` first, naming keys through `api_key_env`; literal keys are rejected\n3. Before exposing it beyond one machine, enable sign-in in `auth.json`, set exact `cors_origins` and set `BACKEND_HOST=127.0.0.1` where loopback is wanted\n4. Run 1.4.10 or later. Earlier versions carry CVE-2026-51870 (shell tool RCE, fixed in 1.4.1) and CVE-2026-58168 (multi-user MCP bypass)\n5. Set `sandbox_allow_subprocess` to false where generated code must run only in the runner sidecar or bubblewrap\n\n## Questions\n\n### Which is better for AI agents, Caddy or DeepTutor?\n\nDeepTutor scores 62.7 (B) on agent readiness against Caddy's 16.7 (F), and leads in 6 of 7 scored categories.\n\n### Are Caddy and DeepTutor open source?\n\nNo open-source release is listed for Caddy. DeepTutor is open source (Apache-2.0).\n\n\n## For agents\n\n- This comparison as JSON: https://www.anchorterminal.com/compare/caddy-app-vs-deeptutor.json, and with the fewest tokens: https://www.anchorterminal.com/compare/caddy-app-vs-deeptutor.min.md\n- Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {\"a\": \"caddy-app\", \"b\": \"deeptutor\"}`.
