Popular Tools for Documenting and Sharing React Components

1. Bit

Bit is a platform for sharing components. It is an open‑source tool that lets you package components with all files and dependencies and run them out‑of‑the‑box in different applications.

With Bit you can share components across apps, discover them via a component hub, search by context, bundle size or dependencies, and view rendered snapshots.

When you open a component detail page, Bit provides an interactive live preview where you can edit the source code (JS or MD) and debug.

Install shared components with npm or Yarn, or develop and install directly with Bit, enabling team collaboration.

Styleguidist is an independent React component development environment with hot‑reloading, automatic compilation, prop‑type tables, and editable examples written in MD files; it supports ES6, Flow, TypeScript and Create React App.

3. CodeSandbox, StackBlitz & friends

Online component playgrounds such as CodeSandbox and StackBlitz let you quickly create, run, and share small projects, providing live preview and automatic dependency installation.

StackBlitz, powered by Visual Studio Code, works as a web IDE for Angular and React projects, compiling and hot‑reloading on the fly.
