React Router

React Router DOM provides browser routing for React applications, including routes, links, outlets, and navigation used to connect authentication and application pages. It is part of React Router, which the official documentation describes as a standards-focused, multi-strategy router that can be deployed in different environments.

React is a JavaScript library for building web and native user interfaces. It uses declarative views that update the appropriate components when application data changes, and lets developers compose encapsulated, state-managing components into larger interfaces. React code can use JSX, an HTML-like syntax for defining interface elements, although JSX is optional. The library is designed for gradual adoption, can render on the server with Node, and supports mobile applications through React Native. Its core repository is developed openly on GitHub under the MIT license.

Next.js is an open-source React framework developed by Vercel for building full-stack web applications. It extends React with server rendering, static-site generation, hybrid rendering, components, and routing, and integrates Rust-based JavaScript tooling for builds. The project provides documentation, a learning course, a showcase, community discussions, and contribution guidelines.

React Native is an open-source framework for building native applications with React. JavaScript components, declarative UI, hooks, and Suspense are rendered through native platform UI on Android, iOS, and other platforms, while Fast Refresh applies JavaScript changes without rebuilding the native app. Native Modules allow JavaScript code to call platform code directly, and the framework can be adopted incrementally in existing applications or used with production frameworks such as Expo. React Native is developed by companies and individual core contributors and is distributed under the MIT license.

9router is a local gateway between AI applications and model providers. It exposes one OpenAI-compatible endpoint, supports provider fallback tiers, tracks usage, and compresses tool outputs.
