## Which one, for what

### Crush (C)

Good for: Developers who want a Go terminal agent with a wide provider list, local models and Claude Code-compatible hooks.

Ahead on:
- Reliability, 54 against 45
- Schema & documentation, 65 against 30
- Agent ergonomics, 52 against 5
- Security & auth, 44 against 36
- Payments & pricing, 55 against 30
- Maintenance & community, 82 against 58

Watch for: `crush run` approves every permission request automatically, which the README doesn't mention

### Unstoppable (F)

Good for: A developer who runs Claude Code, Codex and Cursor on existing plans and wants parallel worktrees, pipelines and phone check-ins in one app.

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

Watch for: No API, MCP server, SDK or documented CLI for an outside agent. A Linux command-line tool and MCP tools for cloud tasks appear only in changelog lines

## Verdicts

**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.

**Unstoppable.** Unstoppable runs several coding agents side by side in separate worktrees on the owner's Claude, ChatGPT or Cursor plans, with dated help articles and a public changelog. It has no API, MCP server or documented command an outside agent can call, every chat starts in Full access, and its pages disagree on which parts need a paid plan.

## Before you call either

### 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

### Unstoppable

1. Don't plan to drive Unstoppable from another agent. It has no documented API, MCP server or CLI. Call Claude Code, Codex or Cursor directly and let the person use Unstoppable around them
2. Inside Unstoppable, check the approval mode before acting. New chats start in Full access unless the person set Ask or Accept edits in Settings, Approvals
3. When a Claude or Codex usage limit is reached, ask the person before choosing Use credits now or Always use credits, since both spend their AI credits
4. Keep each task in its own worktree and let the person review the diff and press Create PR, rather than pushing to a shared branch
