Google Antigravity
Google's agent-first IDE: delegates complex coding tasks to autonomous Gemini agents.
Google Antigravity is an IDE developed by Google, released in November 2025 alongside Gemini 3. It is a fork of VS Code designed from the ground up to be "agent-first": instead of assisting the developer, autonomous AI agents (Gemini 3.1 Pro and Gemini 3 Flash) plan, execute, validate, and iterate complex programming tasks independently. It also supports Claude Sonnet 4.6 and Claude Opus 4.6. It includes native integration with Google Stitch (UI design) via MCP. Currently in free preview.

- ▸Integrar diseño UI con Google Stitch directamente en el IDE
- ▸Usar agentes de Gemini o Claude para programar de forma independiente
You have the code. What about the server?
produfy gives your agent an MCP to ship the app: its own server, a wired-up PostgreSQL and an HTTPS URL in about 90 seconds, with one-command rollback when something breaks. Still on the waitlist.
