## 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.

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

### MiniMax Code (B)

Good for: Scripted coding runs on MiniMax's models or any compatible model, driven by JSON output and exit codes.

Ahead on:
- Reliability, 63 against 43
- Payments & pricing, 60 against 30
- Maintenance & community, 77 against 68
- Transparency & trust, 61 against 51

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

Watch for: Pre-1.0 and labelled a source preview, with npm at 0.6.12 and the public source at 0.6.5

## 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.

**MiniMax Code.** An MIT-licensed terminal coding agent with a headless mode that returns versioned JSON, documented exit codes and an ACP server, and telemetry off by default. It's pre-1.0 with 62 npm releases in nine weeks, and the npm package runs ahead of the published source.

## 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

### MiniMax Code

1. Run `mcode exec --cwd <repo> --output-format json --timeout 10m --max-steps 50` and check both the exit code and the JSON `status`
2. Keep `--permission full` and `off` for a container or throwaway workspace. The default `smart` fails when it would need a person
3. Set `MCODE_PROVIDER_API_KEY` and add a provider for BYOK. M Plan models need a browser sign-in with `mcode login --region global`
4. Set `MINIMAX_DATA_DIR` per CI runner. Keys and sessions live in `~/.minimax` by default
5. Pin a version. npm published 62 releases in nine weeks and the public source trails it
