Remix is the fully-stacked web framework.

Remix brings together a server runtime, routing, authentication, sessions, database integrations, a UI framework, asset compilation, dynamic styling, and accessible components in a cohesive stack built on Web APIs.

Everything you need, all in a single package. Remix provides the core systems you need to build, run, and maintain a modern web application. Use the complete framework or reach for individual packages when you need them.

- Server & runtime: Fetch-based HTTP servers and portable Web APIs that run across modern JavaScript runtimes.

- Routing & middleware: Typed routes, controllers, request context, and composable middleware from one coherent model.

- Data & databases: Runtime validation and typed relational data for SQLite, PostgreSQL, and MySQL.

- Auth & sessions: Authentication, OAuth, cookies, sessions, storage adapters, and security middleware.

- UI framework, components & styling: Server rendering, HTML-first Frames, composable styles, accessible components, forms, and animation.

- Assets & development: On-demand TypeScript, JSX, and CSS compilation with HMR and a first-party CLI.

- Testing & production: A test framework, logging, compression, static files, and production server tooling.

A bigger toolkit with a smaller mental model.

Web APIs throughout.

Runtime-first.

Composable packages.

One coherent model.
