All the news from the Google I/O 2026 Developer keynote

Google launched the Gemini 3.5 series and introduced Antigravity agent-first development platform. The platform now includes Android CLI tools, Android Bench evaluation leaderboard, and an automated Migration agent that converts frameworks to native Kotlin code. Chrome DevTools for agents, HTML-in-Canvas API, and WebMCP are proposed for web development. These tools enable browser-based AI agents to execute tasks directly in the browser. Builders can now deploy AI agents across mobile and web with native code and real-time evaluation metrics.
