## Which one, for what

### Mistral Vibe CLI (B)

Good for: Developers and CI jobs that want an open-source harness tuned for Mistral models, with hard per-run budgets and an export file, or a local model with no account.

Ahead on:
- Reliability, 69 against 45
- Agent ergonomics, 84 against 79
- Payments & pricing, 60 against 20
- Transparency & trust, 79 against 57

Also in its favour:
- Free to start without a card
- Open source

Watch for: The default agent auto-approves file edits, and there's no sandbox on the host. Isolation needs the experimental `--agent-socket` server or a container

### Muse Code (C)

Good for: Developers who want Meta's Muse models, Muse Wonder Full included, in a terminal or CI agent with the sandbox and approvals on from the first run.

Ahead on:
- Schema & documentation, 84 against 76
- Security & auth, 67 against 58

Also in its favour:
- No incidents deducted, where Mistral Vibe CLI loses 8 points for them

Watch for: Closed source, with no public CI or issue tracker for the CLI found and release notes that carry no dates

## Verdicts

**Mistral Vibe CLI.** Apache-2.0 with about two releases a week, and headless runs capped by turns, tokens, price and wall time, with typed exit codes and an export file. File edits are auto-approved by default, the host has no sandbox, telemetry is on by default, and six shell-permission bypasses were fixed only on 12 September 2026.

**Muse Code.** Muse Code runs with approvals and an OS sandbox on by default, per-host network approval, an append-only event log and a headless mode with documented exit codes. It is the only route to Muse Wonder Full. It is closed source with undated release notes and no free route, and subscriptions allow training on code unless Contributor mode is turned off.

## Before you call either

### Mistral Vibe CLI

1. Pass `--agent` on every `-p` run (`plan` is read-only). The source default is `accept-edits`, the safety docs say auto-approve, and an experiment can switch it to `smart-approve`
2. Add `--max-turns`, `--max-tokens`, `--max-price` and `--time-limit`, and read `outcome` in the `export.json` that `--output-dir` writes. Exit 3 means a limit or a refusal
3. Run in a container or behind `--agent-socket` before using `--auto-approve`. Vibe has no sandbox of its own on the host
4. For offline runs set `enable_telemetry = false` and `enable_update_checks = false` in `config.toml`. The docs' `enable_auto_update` isn't the key the code reads
5. Use 2.25.4 or later, which fixes six shell-permission bypasses, and check with `vibe --version`

### Muse Code

1. Set `META_API_KEY` for headless runs. Browser sign-in isn't available in CI or for Meta Managed Accounts
2. Gate on your own test command, not the exit code. `muse exec` returns 0 when the turn completes even if tests still fail
3. Pass `--max-model-steps` on unattended runs so a stuck task can't loop
4. Prefer `--disable-approval` to `--yolo` in CI so the sandbox stays on. On Linux the runner needs a working bubblewrap and a non-musl build
5. Turn Contributor mode off in `/settings` before a subscription session touches private code
