## What it is
The official repository for the Chrome DevTools Protocol (CDP), providing protocol definitions, documentation, and TypeScript type definitions for instrumenting, inspecting, debugging, and profiling Chromium-based browsers. It is published as the devtools-protocol npm module for use in tooling built on top of CDP.

## Use cases
- build browser automation tools on top of Chrome DevTools Protocol
- get TypeScript types for CDP commands and events
- debug and profile Chromium or Node.js apps programmatically
- browse CDP domain documentation and protocol versions
- instrument network, DOM, and debugger activity in Chrome
- write a CDP client library in JavaScript or TypeScript

## When to choose
- you are building tooling that speaks the Chrome DevTools Protocol
- you need typed definitions for CDP domains, commands, and events
- you want to debug or profile Chromium-based browsers or Node.js programmatically

## When to avoid
- you need a high-level browser automation API like Puppeteer or Playwright rather than raw protocol definitions
- you need to debug non-Chromium browsers that don't support CDP
- you want a stable, backwards-compatible API surface — tip-of-tree protocol changes frequently
