devtools-frontend

The devtools-frontend project is the open-source, standalone UI layer for Chrome DevTools, providing the interface that web developers use to debug, profile, and inspect web applications. It is designed for both browser vendors integrating DevTools into their products and for developers building custom debugging tools. Its interest lies in being a large-scale, real-world example of a complex web application built with modern frontend technologies, offering deep insight into browser internals and developer tooling.
