About Web Maker
Web Maker is a free, open-source offline frontend code editor available as a Chrome extension and open web app. It functions as a local playground for web experiments, comparable to tools like CodePen or JSFiddle but designed to run entirely on a user's system without an internet connection.
Users can write, test, and save frontend code using supported preprocessors for HTML (Pug, Markdown), CSS (SCSS, LESS, Stylus, Atomic CSS), and JavaScript (ES6, TypeScript, CoffeeScript). The tool includes an inbuilt console, auto-save, code auto-completion, and project import/export functionality, making it suitable for quick prototyping, learning, and testing frontend code snippets without relying on cloud services.
