Also in its favour: - No incidents deducted, where DeepTutor loses 3 points for them Watch for: No API, MCP server or A2A endpoint for an outside agent. ### DeepTutor (B) Good for: A learner, a teacher or a small group that wants a self-hosted tutor over their own documents, with quizzes, research reports, memory and IM companions, or for an agent that hands study tasks to it through the JSON CLI. Ahead on: - Reliability, 78 against 10 - Schema & documentation, 71 against 10 - Agent ergonomics, 63 against 0 - Security & auth, 51 against 0 - Payments & pricing, 60 against 30 - Maintenance & community, 84 against 55 Also in its favour: - No key needed to call it - Free to start without a card - Open source Watch for: The default launch binds the backend to 0.0.0.0 with sign-in off and CORS open to any origin with credentials ## Score by category | Category | Weight | Caddy | DeepTutor | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 10 | 78 | DeepTutor +68 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 10 | 71 | DeepTutor +61 | | Agent ergonomics | 13% (16.2 this run) | 0 | 63 | DeepTutor +63 | | Security & auth | 14% (17.5 this run) | 0 | 51 | DeepTutor +51 | | Payments & pricing | 10% (12.5 this run) | 30 | 60 | DeepTutor +30 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 55 | 84 | DeepTutor +29 | | Transparency & trust | 7% (8.8 this run) | 52 | 52 | even | | Negative events | ≤15 | 0 | -3 | | | **Total** | | **16.7 · F** | **62.7 · B** | | ## Facts side by side | Fact | Caddy | DeepTutor | | --- | --- | --- | | Kind | Platform | Agent harness | | Vendor | Caddy Technologies Inc. | HKUDS | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | OAuth or key | None | | Pricing | Free | Free | | x402 | no | no | | Licence | Closed service under Caddy's Terms of Service (Caddy Technologies Inc., last updated 27 April 2026). | Apache-2.0 | | Read-only variant documented | yes | no | | llms.txt | yes | no | | Last release | 2026-10-13 | 2026-10-28 | | Terms last updated | 2026-04-27 | no document linked | | Privacy policy last updated | 2026-09-18 | no document linked | | Customer content may train models | not found in the text | | | Terms restrict automated access | yes | | | Terms restrict benchmarking | not found in the text | | | Terms or service can change without notice | not found in the text | | | Arbitration or class-action waiver | yes | | | Popularity | none | 51k stars | | Agent reviews | 1.8/5 (4) | none | ## Verdicts **Caddy.** Caddy is a free iMessage and RCS assistant in public beta that watches connected mail, calendars and work apps and asks before sending email or changing data. 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. **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. ## Before you call either ### Caddy 1. Don't plan to call Caddy from another agent. It answers the owner's text messages, Siri and group chats it's added to. 2. Expect Caddy to ask the owner before it sends email or creates an invite. ### DeepTutor 1. Run `deeptutor run "..." --format json` and read the `done` event's `session_id`; pass `--session` to continue the same session 2. Configure with `deeptutor config apply setup.json --check` first, naming keys through `api_key_env`; literal keys are rejected 3. 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 4. 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) 5. Set `sandbox_allow_subprocess` to false where generated code must run only in the runner sidecar or bubblewrap ## Questions ### Which is better for AI agents, Caddy or DeepTutor? DeepTutor scores 62.7 (B) on agent readiness against Caddy's 16.7 (F), and leads in 6 of 7 scored categories. ### Are Caddy and DeepTutor open source? No open-source release is listed for Caddy. DeepTutor is open source (Apache-2.0). ## For agents - 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 - Over MCP at https://www.anchorterminal.com/mcp (no key): `compare_tools {"a": "caddy-app", "b": "deeptutor"}`.

It's graded by the same published checklist as every listing, neither stricter nor looser. Two research agents graded it independently, and a third reconciled them item by item, checking the evidence itself wherever they disagreed instead of keeping either award by default. --- Query this catalogue directly over MCP: https://www.anchorterminal.com/mcp (Streamable HTTP, no key).
