aux-devtool is a free Chrome extension developed by huguangyu000. It falls under the category of Browsers and is specifically classified as an Add-ons & Tools subcategory. This extension is designed to assist developers in visually writing code, with a focus on CSS and other enhancements.

aux is a low code development tool that is built on the React front-end framework. It offers visual coding capabilities by utilizing source code rewriting. Developed by bytedance, Inc., aux provides features such as code insertion, editing, deletion, and preview based on React components. It also includes a jump function that integrates with the IDE.

One of the key features of aux is its powerful CSS editing capabilities for web pages. It requires extensive metadata for CSS stylesheets, which cannot be obtained through the browser's API. To overcome this limitation, aux leverages the Chrome DevTools Protocol through the debugger API of the Chrome extension. This allows aux to retrieve CSS style information and provide a seamless visual coding experience for front-end developers.
