Crush vs Mistral Vibe CLI

Crush

Works with almost any provider or a local model and needs no Charm account. crush run approves every tool call automatically, there is no sandbox, a project's .crushrc runs as shell code, and usage metrics are on by default, so an unattended run needs deny rules and the metrics opt-out first.

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.

Crush

1. Add permissions deny rules or a PreToolUse hook before crush run. It approves every permission request in its session
2. Read .crushrc, crushrc and crush.json in a cloned repository before running Crush there. They execute as shell code at startup
3. Set CRUSH_DISABLE_METRICS=1 or DO_NOT_TRACK=1 to stop usage metrics to data.charm.land
4. Wrap crush run in your own timeout. It has no turn, time or cost limit flag
5. Configure a provider by environment variable or crushrc first. With none, crush run exits with an error asking for interactive setup

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
