Building browser extensions is often painful — outdated boilerplate, complex manifest setup, and no good local dev environment. extn fixes this by giving you: ⚡ Hot Module Replacement (HMR) for instant updates 🧪 Live Preview — automatically opens Chrome with your extension loaded 📦 Templates for Vanilla TS, React TS, and Vue TS 🏗️ Production-ready scaffolding 🔒 Manifest v3 validation 🛠️ Vite-powered builds 🧹 No more manual reloading Everything works out of the box.
