Extro
Next.js for Chrome extensions
Build Chrome extensions with the same developer experience you'd expect from a modern web framework. File-based extension surfaces, automatic Manifest V3 generation, React Fast Refresh, routing, TypeScript, and a one-command setup.
Hey Product Hunt 👋
I'm Sahil, creator of Extro.
I started building Extro after noticing Plasmo had largely stopped being maintained. While tools like WXT and CRXJS exist, I wanted a framework that brought a more familiar web development experience to Chrome extensions.
With Extro, you create folders inside src/app and they become extension surfaces automatically. Popup, options, side panel, background scripts, and content scripts are all discovered from your file structure, and Manifest V3 is generated for you.
It also includes file-based routing, dynamic routes, layouts, React Fast Refresh, TypeScript support, and React-powered content scripts with Shadow DOM support.
Extro is open source, MIT licensed, and built solo. It's currently in a pre-stable stage, and there are still quite a few things on the roadmap before the first stable release, including Firefox support and other improvements based on community feedback.
I'd love to hear what extension developers think, what feels missing, and what would make the framework more useful for real-world projects.
Thanks for checking it out ❤️
