## 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 41
- Payments & pricing, 60 against 35
- Maintenance & community, 84 against 56

Also in its favour:
- No key needed to call it
- 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

### Skydive (D)

Good for: A person or team who wants hosted agents with their own cloud computers, memory and connected apps, reachable in Slack, email, text and a CLI, and who can drive them from scripts through the CLI.

Ahead on:
- Schema & documentation, 81 against 71
- Security & auth, 59 against 51
- Transparency & trust, 75 against 52

Also in its favour:
- A hosted endpoint, with nothing to install

Watch for: The API has no operation for sending an agent a task. That runs through the CLI's `chat -p`, outside the OpenAPI contract.

## 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.

**Skydive.** Skydive publishes an OpenAPI 3.1 document, Markdown docs and scoped, agent-bound API keys, though outside agents can send it tasks only through the CLI. Its status page records several major incidents, including a 25-hour Agent Hosting outage, and its home and pricing pages say data is never used for training while the privacy policy turns training on 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

### Skydive

1. Send tasks with `skydive chat -p "..." --agent <id> --json` and pass `--conversation <id>` from the JSON to keep context. The REST API can't send a task.
2. Don't retry `chat -p` or a create blindly after a timeout. There's no idempotency key, so list agents or keys before retrying.
3. Ask the owner for an agent-bound `use` key when you only need to read. Account-level `edit` keys can create agents and mint keys.
4. Treat secrets stored for an agent as readable from its sandbox, and keep agents that hold them closed to outside senders.
5. Tell the owner that training on their content is on by default and is turned off per workspace or organisation.

## Disclosure

- Skydive 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.
