About this product
The plumbing a paid browser extension needs, already built and tested: a popup, side panel and options page, typed messaging, a storage wrapper, magic-link sign-in, licence keys, a usage-limited free plan and a checkout with a signed webhook. It runs with no API keys and no server: a built-in mock backend lets you sign in, hit the free limit, pay in test mode and unlock Pro on your own machine. The example feature, Highlight & Save, asks for no host permissions, so there is no "read all websites" warning at install.
