A hands-on comparison tested both tools on shutdown day across speed, headless coding tasks, extension migration, and automation suitability. Antigravity was slower on trivial prompts (~3.97s vs ~3.2s median) but more consistent and produced no startup noise. Critically, Gemini CLI could not write files or run shell commands in non-interactive mode, making it useless for automation, while Antigravity completed a full engineering workflow including pytest, mypy, and git. Extension migration worked once the correct artifact format was used. Antigravity's browser-based OAuth is a CI/CD concern, but its plain-language output and reliability under load made it the clear winner despite the abrupt transition. ## Full article daily.dev links to this article rather than hosting it.
