Gemini CLI vs. Antigravity: What works, not the spec sheet

▤ Summary

Google has replaced its Gemini CLI with Antigravity CLI and the article tests whether the new tool actually works better in practice. The comparison focuses on speed, scripting support, extension migration, and automation behavior across both tools. Antigravity performs better for headless coding tasks because it can write files and run commands, while Gemini CLI fails in non-interactive mode. The article also notes that Antigravity offers a cleaner user experience and migrated a sample extension successfully. Overall, the piece argues that Antigravity is the more usable tool for developers despite some unanswered questions about CI and browser-based login.
