What is the best React stack for building AI-centric products in 2026?

The question is about React.js .

Answer:
The most effective React stack for AI-focused products in 2026 combines Next.js for full-stack rendering and API routes, TypeScript for type safety, and the Vercel AI SDK for streaming LLM responses to the front end. Supabase with pgvector manages vector storage for RAG features. Tailwind CSS and shadcn/ui speed up AI chat and dashboard UI development. The OpenAI or Anthropic API acts as the LLM backend for most AI product interactions.
