GitHub Sponsors Profile
I'm building Extension.js, a developer tool that makes it very easy to develop cross-browser extensions.
Browser extensions power privacy tools, AI assistants, devtools, productivity workflows ā but building them has been painful for too long. Iām here to change that.
With Extension.js, developers can go from pnpm extension create to publishing in the Chrome, Firefox, and Edge stores ā all with a unified, modern developer experience.
About Extension.js
š§° Used in 600+ active projects as per GitHub
āļø Templates for React, Vue, Svelte, Preact, vanilla TypeScript, and vanilla JS
š Built-in support for WebExtension APIs and Manifest V2/V3
𧬠Works cross-browser (Chrome/Edge/Firefox) with a single manifest file
