Backends • **Assistant Cloud**: managed chat persistence and analytics. Deploy with the Cloud Starter template; bring any model/provider. • **AI SDK**: integration with Vercel AI SDK; connect to any supported provider. • **LangGraph**: integration with LangGraph and LangGraph Cloud; connect via LangChain providers. • **Mastra**: integration with Mastra agents/workflows/RAG; model routing via Vercel AI SDK; optional Mastra Cloud. • **Custom**: use assistant-ui on top of your own backend/streaming protocol. Customization assistant-ui takes a Radix-style approach: instead of a single monolithic chat component, you compose primitives and bring your own styles. We provide a great starter config; you control everything else. Sample customization to make a Perplexity lookalike: Traction assistant-ui is the most popular UI library for building AI chat. Hundreds of companies and projects use assistant-ui to build in-app AI assistants, including , , , , , , , , , , and more.
