## 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:
- Payments & pricing, 60 against 40

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

### GitHub Copilot CLI (C)

Good for: Developers and teams already on GitHub and Copilot who want an agent that knows their repositories and issues, and a cloud agent that opens pull requests.

Ahead on:
- Schema & documentation, 72 against 64
- Agent ergonomics, 72 against 62
- Security & auth, 60 against 54
- Transparency & trust, 68 against 55

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

Watch for: Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026

## 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.

**GitHub Copilot CLI.** Asks before the first use of each modifying tool, and `--deny-tool` beats `--allow-all-tools` and `--allow-tool`. Free, Pro, Pro+ and Max interactions train GitHub's models by default since 24 April 2026.

## 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

### GitHub Copilot CLI

1. Pass `--deny-tool` for anything destructive. It wins over `--allow-all-tools` and `--allow-tool`
2. Turn on the sandbox with `/sandbox enable` or `--sandbox`. It's off unless you opt in
3. Turn off model training in Copilot settings on Free, Pro, Pro+ and Max. It's on by default since 24 April 2026
4. Run 1.0.88 or later where enterprise policy matters. Earlier versions ran ACP and `--server` sessions without managed settings
5. Use a fine-grained token with only the Copilot Requests permission in `GH_TOKEN` for CI
