Verdicts

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.

Zapia

Zapia is a personal assistant app for iOS, Android and the web with a free plan that isn't a trial, weekly iOS releases and explicit confirmation before anything that writes. No outside agent can call it, and no status page, security contact or hosting location was found.

Before you call either

DeepTutor

  1. Run deeptutor run <capability> "..." --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

Zapia

  1. Don't plan to call Zapia from another agent. It answers only in its own app and on the web, and the terms forbid unauthorised automated access.
  2. Tell the owner that Pro and Ultra trials become paid after 7 days unless cancelled in the app store.

Other comparisons with DeepTutor or Zapia

Disclosure

Zapia competes with LocalGhost, which Anchor Terminal's founder builds. 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.

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
