Ahead on: - Reliability, 78 against 5 - Schema & documentation, 71 against 10 - Agent ergonomics, 63 against 0 - Security & auth, 51 against 0 - Payments & pricing, 60 against 20 - Maintenance & community, 84 against 2 - Transparency & trust, 52 against 29 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 ### szn (F) Good for: A person who wants calls, emails and bookings done for them and has an access code. Also in its favour: - No incidents deducted, where DeepTutor loses 3 points for them Watch for: Early access by access code only. ## Score by category | Category | Weight | DeepTutor | szn | Edge | | --- | --- | --- | --- | --- | | Reliability | 16% (20 this run) | 78 | 5 | DeepTutor +73 | | Performance | 10%, pending | pending | pending | not scored in this run | | Schema & documentation | 13% (16.2 this run) | 71 | 10 | DeepTutor +61 | | Agent ergonomics | 13% (16.2 this run) | 63 | 0 | DeepTutor +63 | | Security & auth | 14% (17.5 this run) | 51 | 0 | DeepTutor +51 | | Payments & pricing | 10% (12.5 this run) | 60 | 20 | DeepTutor +40 | | Task success | 10%, pending | pending | pending | not scored in this run | | Maintenance & community | 7% (8.8 this run) | 84 | 2 | DeepTutor +82 | | Transparency & trust | 7% (8.8 this run) | 52 | 29 | DeepTutor +23 | | Negative events | ≤15 | -3 | 0 | | | **Total** | | **62.7 · B** | **7.8 · F** | | ## Facts side by side | Fact | DeepTutor | szn | | --- | --- | --- | | Kind | Agent harness | Platform | | Vendor | HKUDS | Nomadic Futures | | Hosted endpoint | no (local only) | no (local only) | | Transports | | | | Auth | None | OAuth or key | | Pricing | Free | Free | | x402 | no | no | | Licence | Apache-2.0 | Closed service.

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. **szn.** szn is an errand assistant in early access that makes calls, sends emails and books for its owner, free during the preview for people with an access code. No outside agent can call it, no terms of service or legal entity appear in its policies, and its privacy policy says nothing on training. ## Before you call either ### 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 ### szn 1. Don't plan to call szn from another agent. It answers only its web app, iMessage, SMS and email for the owner. 2. Tell the owner they need an access code to start, and that the acceptable use policy makes them responsible for confirming actions. ## Questions ### Which is better for AI agents, DeepTutor or szn?

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).
