CodeFusion is an efficient tool designed for web developers who need to merge JavaScript, Python, and CSS files seamlessly. Operating as a Chrome add-on, it allows users to simply drag and drop their code files or entire folders, automatically excluding unnecessary directories such as node_modules and dist. This feature is particularly useful for preparing code for AI workflows or for generating quick previews without the hassle of complex setups.

The application provides a clean and readable output, ensuring that the fused code is easy to work with. Users can toggle between different code types and enjoy the convenience of copying results with a single click. Since everything runs locally in the browser, CodeFusion guarantees fast performance and privacy, making it a hassle-free solution for developers looking to optimize their coding processes.
