## Which one, for what

### 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 32
- Schema & documentation, 71 against 33
- Agent ergonomics, 63 against 57
- Security & auth, 51 against 34
- Maintenance & community, 84 against 15

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

### Leon (E)

Good for: A developer who wants a self-hosted assistant with memory, computer use and a local model, and who will read the source.

Ahead on:
- Transparency & trust, 63 against 52

Also in its favour:
- No incidents deducted, where DeepTutor loses 3 points for them

Watch for: No tagged release of the core since 1.0.0-beta.8 on 1 May 2023. The 2.0 Developer Preview is installed by cloning the develop branch

## 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.

**Leon.** Connected-app credentials are encrypted per profile and the Gmail connection is read-only. The 2.0 Developer Preview has no tagged release, runs tools and a 30-minute proactive pulse with no approval step, listens on every network interface with client authentication off, and sends telemetry by default.

## 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

### Leon

1. Clone the develop branch for 2.0. `npm install --global @leon-ai/cli` and docs.getleon.ai install and describe the legacy 1.0 betas
2. Set `client_interface.auth.enabled: true` and a `LEON_PROFILE_TOKEN` before the machine joins a shared network. The server binds 0.0.0.0
3. Set `telemetry_enabled: false` and `runtime.pulse_enabled: false` in the profile `config.yml` for an unattended or private run
4. Use `availability.tools.allowed` to limit tools. Shell, file writes, computer use and browser control are otherwise available to the agent with no approval prompt
5. Back up `LEON_CONNECTIONS_ENCRYPTION_KEY` from the profile `.env`. Without it the stored connections cannot be read
