NOT ON THE CURRENT EDITION
This blip is not on the current edition of the Radar. If it was on one of the last few editions, it is likely that it is still relevant. If the blip is older, it might no longer be relevant and our assessment might be different today. Unfortunately, we simply don't have the bandwidth to continuously review blips from previous editions of the Radar.

assistant-ui is an open-source TypeScript and React library for AI chat interfaces. It handles the complex parts of chat UI implementation — such as streaming, state management for message editing and branch switching and common UX features — while allowing developers to design their own components using Radix primitives. It supports integration with popular runtimes, including Vercel AI SDK and LangGraph, and offers customizable runtime solutions for complex use cases. We’ve successfully built a simple chat interface with assistant-ui and have been pleased with the results.
