Interactions are used to improve Google products unless users opt out, and a headless run exits 0 when a tool is denied.\n\n**Gemini CLI.** Apache-2.0, with 16 stable releases since 3 July and documented headless output. Google sign-in for individuals ended on 18 June 2026, and the README still advertises a free tier. Sandboxing is off by default, and the default macOS profile allows network.\n\n## Before you call either\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### Gemini CLI\n\n1. Set `GEMINI_TRUST_WORKSPACE` to true only for trusted inputs in CI. Since 0.39.1 headless mode doesn't trust a folder on its own\n2. Turn on the sandbox with `-s` or `tools.sandbox`, and pick a proxied Seatbelt profile on macOS to cut network\n3. Set `privacy.usageStatisticsEnabled` to false to stop usage statistics\n4. Since 0.63.0, plans run without interactive confirmation in non-interactive mode, so set the approval mode explicitly before a headless run\n5. Authenticate with a paid Gemini API key or Vertex credentials. A Google sign-in works only for Code Assist Standard or Enterprise licences\n\n## Questions\n\n### Which is better for AI agents, Antigravity CLI or Gemini CLI?\n\nGemini CLI scores 66.7 (B) on agent readiness against Antigravity CLI's 57.7 (C), and leads in 5 of 7 scored categories. Antigravity CLI leads on payments \u0026 pricing.\n\n### Are Antigravity CLI and Gemini CLI open source?\n\nNo open-source release is listed for Antigravity CLI.
