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.

Del

Del is a hosted texting assistant and task workspace across iMessage, WhatsApp, Telegram, SMS, Discord and Slack, with a near-daily public changelog and a card-free 14-day trial. No outside agent can call it, no status page or security contact was found, and recent updates let some email actions skip approval.

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

Del

  1. Don't plan to call Del from another agent. It answers only the owner's messaging threads and web workspace.
  2. Tell the owner web browsing tasks are limited to five a month on Standard and unlimited on Pro.

Disclosure

Del 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.

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.
