@inferencesh

A batteries-included shadcn registry from inference.sh providing a complete AI agent UI runtime. Key blocks: Agent (full wired agent with streaming and tool lifecycle), Chat (container, messages, composer, status indicators), Tools (tool invocation UI: pending, in-progress, human-in-the-loop approval, results), Widgets (renders declarative JSON UI nodes as interactive components), Markdown (high-fidelity with code blocks and zoomable images), Code Block, Steps, Sidebar Light, Table of Contents, YouTube Embed, and Zoomable Image. Open-source, MIT. Use for: building production AI agent interfaces in Next.js that need streaming, tool rendering, and human-in-the-loop approvals without wiring each piece from scratch.
