Builder.io Open-Sources Agent-Native TypeScript Framework

Builder.io released Agent-Native, an MIT-licensed full-stack TypeScript framework where humans and AI agents share one action layer. Actions defined once via defineAction become React hooks, LLM tools, MCP servers and HTTP endpoints.

• Single Action primitive: one code for UI, LLM tools, MCP and REST
• Agent gets real-time UI context and shared data
• Includes PostgreSQL/PGlite, cron automation, RBAC and agent memory
• MIT license, repo BuilderIO/agent-native on GitHub
