A self-contained launch kit for selling Chrome, Edge, and Firefox extensions with offline license verification, Paddle payments, and a Cloudflare Worker.

Landing page captured for the 2026-09-20 issue.
For
Browser-extension developers selling paid features
Worth noticing
The sandbox exposes trial, device-seat, refund, tamper, and simulated Worker-outage states.

Field notes

The package separates the extension, licensing Worker, static site, configuration, and supporting scripts, with feature entitlements derived from signed licenses rather than a stored Pro flag. Its public sandbox walks through a seven-day trial, additional device seats, refunds, token tampering, and a simulated Worker outage. The page also shows TypeScript and WebCrypto examples for local ES256 verification.
