## Which one, for what

### Agent Zero (C)

Good for: A technical owner who wants an agent with its own Linux machine, reachable from Telegram, WhatsApp or email, with scheduled tasks and editable memory.

Ahead on:
- Agent ergonomics, 62 against 52
- Security & auth, 54 against 44
- Payments & pricing, 60 against 55

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

Watch for: No approval step before shell commands, file changes or outgoing messages. Tool Access defaults to allow

### 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:
- Maintenance & community, 82 against 75

Also in its favour:
- Free to start without a card
- No incidents deducted, where Agent Zero loses 6 points for them

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

## Verdicts

**Agent Zero.** Self-hosted under the MIT licence, with nine releases in the 90 days to 12 October 2026 and breaking changes listed in the release notes. The agent runs shell commands in its container with no approval step, the web interface has no login by default, and five CVEs from the past year have no published GitHub advisory.

**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.

## Before you call either

### Agent Zero

1. Set a UI login and password in Settings before publishing the port or opening a tunnel. The default has none
2. Fill `allowed_users`, `allowed_numbers` or `sender_whitelist` before enabling a channel. An empty list accepts every sender
3. Enable the Infection Check plugin when the agent reads mail, web pages or MCP results. It ships disabled
4. Run v2.12 or later. It fixes a Telegram webhook authentication bypass and a WhatsApp media path traversal
5. Call `POST /api_message` with the `X-API-KEY` header. The token changes when the UI login or password changes

### 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
