Monetized Chrome Extension Boilerplate An out-of-the-box monetization template for Chrome Extensions. It lets developers launch paid extensions within 48 hours, without rebuilding payment, licensing and trial logic from scratch.
The Core Problem: Every paid Chrome Extension requires license validation, trial period management and premium feature gating. This boilerplate infrastructure eats up tons of development time. This template packages all these reusable modules, so developers only need to swap in their own business logic and launch for monetization.
Included Modules
Server-side Licensing System (server/)
Express.js 4.x REST API
License storage powered by Node.js 22 built-in node:sqlite
Secure server-side license validation (the frontend only caches status; access permissions are never hardcoded inside the browser)
Device fingerprint binding to stop license sharing
Download token system (time-limited download links)
Lemon Squeezy Webhook template (auto-create orders and licenses)
Nodemailer email delivery (send license keys via email automatically)
