Vista

Vista is a React framework for building fullstack web applications with integrated UI, APIs, auth, and AI agents.

Vista is a React framework designed to scale from pages to fullstack applications within a single directory and runtime. It provides file-system routing with nested layouts and Server Components by default under the app directory. Developers can build fullstack features using route handlers and typed procedures that are called directly from React Server Components. The framework includes built-in authentication with sessions, OAuth, and fail-closed middleware. It also supports streaming AI agents and retrieval-augmented generation using model providers such as Groq, NIM, and OpenAI.
