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.
