No release since 0.86.2 on 12 February 2026 and no commit since 22 May 2026.\n\n**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.\n\n## Before you call either\n\n### Aider\n\n1. Read `.aider.conf.yml` in any cloned repository before starting aider. Its `test-cmd` and `lint-cmd` run without asking\n2. Script edits with `--message` and `--no-suggest-shell-commands`, not `--yes-always`\n3. Use Python 3.12 or earlier for the PyPI release\n4. Pass `--no-detect-urls` when the prompt holds links you don't want offered for scraping\n5. Check `git log` after a run. Each edit is its own commit\n\n### Antigravity CLI\n\n1. Read the `status` field from `--output-format json` and read stderr too. A tool refused for lack of approval still exits 0\n2. 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\n3. 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\n4. Turn off Enable Telemetry in the Account settings before running on private repositories if Interactions should not be used for product improvement\n5. Set `--print-timeout` explicitly. The docs give a five-minute default, while `agy --help` shows 0s\n\n## Questions\n\n### Which is better for AI agents, Aider or Antigravity CLI?\n\nAntigravity CLI scores 57.7 (C) on agent readiness against Aider's 46.9 (D), and leads in 3 of 7 scored categories. Aider leads on reliability, security \u0026 auth, payments \u0026 pricing and transparency \u0026 trust.\n\n### Are Aider and Antigravity CLI open source?\n\nAider is open source (Apache-2.0).
