BuilderIO Releases Open-Source Framework 'Agent-Native' for Sharing Actions Between Agents and UI

BuilderIO has released Agent-Native, an open-source TypeScript framework that combines agents with dedicated UIs. The core concept of this framework is that each capability is defined once as an action, allowing agents to use it as a tool and UIs to call it from code, utilizing it identically.

Shared Elements:

• Shared actions: Agents and UIs use the same validation, permissions, and implementation.
• Shared data: Agent work results are displayed in the UI, and work done in the UI is accessible to agents.
• Shared application state: Agents receive relevant UI state, such as the current page or selected records.

Key Features and Components: Actions defined via defineAction are exposed across various app surfaces, including React's useActionQuery, HTTP, MCP, A2A, and CLI. The framework includes agent chat, authentication/permission management, skills and memory, automation, agent teams, and a PostgreSQL backend (including PGlite for local development). LLMs, SQL databases, and infrastructure are provided by the user (BYO), and it is released under the MIT license, having recorded 4.8k stars on GitHub.
