Score: 6.3/10 (Innovation: 7, Technical: 6, Documentation: 6, Utility: 6)

AG2B is a client-side agentic runtime that runs the AI agent loop directly in the browser, enabling LLMs to interact with UI elements via tools and scopes. It reuses existing frontend code as agent tools and supports human-in-the-loop approvals, making it a novel combination of frontend frameworks and agent orchestration.

Target audience: frontend devs
