## Which one, for what

### Antigravity CLI (C)

Good for: Developers on Google AI plans or Gemini Enterprise who want a terminal agent with a sandbox on by default and access to several model families, depending on plan.

Ahead on:
- Agent ergonomics, 78 against 67

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

Watch for: Closed source. The repository holds the README, changelog and examples, with no source and no licence file

### Cline (C)

Good for: Developers who want an agent inside VS Code or JetBrains that asks before acting and can roll back, with the same engine in a CLI.

Ahead on:
- Reliability, 80 against 43
- Payments & pricing, 50 against 30
- Maintenance & community, 85 against 68
- Transparency & trust, 61 against 54

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

Watch for: The CLI approves every tool by default outside ACP mode and starts on Cline's own provider

## Verdicts

**Antigravity CLI.** Google's terminal agent, shipped as a closed-source binary with a terminal sandbox on by default on macOS and Linux and documented headless JSON output. Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.

**Cline.** Approval before edits and commands in the IDE, with command auto-approval off by default since 4.0.0. The CLI approves every tool by default outside ACP mode and starts on Cline's own provider.

## Before you call either

### Antigravity CLI

1. Read the `status` field from `--output-format json` and read stderr too. A tool refused for lack of approval still exits 0
2. Pre-approve each shell command and tool a headless run needs with `action(target)` rules under `permissions.allow` in ~/.gemini/antigravity-cli/settings.json, because headless runs cannot ask
3. Export `GEMINI_API_KEY` after setting modelProvider to gemini. The CLI won't start when the key is missing, and setting the variable alone has no effect
4. Turn off Enable Telemetry in the Account settings before running on private repositories if Interactions should not be used for product improvement
5. Set `--print-timeout` explicitly. The docs give a five-minute default, while `agy --help` shows 0s

### Cline

1. Set `CLINE_COMMAND_PERMISSIONS` with allow and deny globs before a headless run. The CLI approves every tool by default
2. Pick a provider with `-P` and a key, or run `cline auth`. The default provider needs a Cline sign-in
3. Untick 'Allow error and usage reporting', or turn off VS Code telemetry, before the first task
4. Pin the CLI version. 2.3.0 was a malicious publish
5. Keep the hub on 127.0.0.1 or set ROOM_SECRET, and run 3.0.30 or later
