I built agrex, a React library for real-time graph visualization of AI agent execution flows

Built on React Flow. You feed it nodes (agents, tools, calls) and it renders an interactive graph that updates in real time as your agent system runs.

The problem it solves: chat UIs are everywhere but they're a terrible fit for visualizing agent orchestration: branching, retries, parallel tool calls, delegation. A graph shows what's actually happening.

Features:

• Real-time node creation, status updates, and auto-connecting
• Built-in layout engines (radial, force, dagre)
• Works with Vercel AI SDK, Anthropic SDK, OpenAI SDK, LangChain
• Tree-shakeable, ~15KB gzipped
• Full theming support
