Extension.js - Modern Cross-browser Extension Framework

Extension.js revolutionizes browser extension development by providing a zero-configuration framework that works across major browsers. It's designed for developers who want to skip the tedious setup process and jump straight into building extensions using modern web technologies like TypeScript, WebAssembly, and popular frameworks like React or Vue. The framework stands out for its plug-and-play nature and built-in support for hot reloading during development.
