What ships in this migration

  • A dedicated Next.js account area for billing and extension setup.
  • Clerk-powered authentication with a single account flow.
  • Polar-backed billing with a 14-day free trial and cancel-anytime portal.
  • A first-party extension token so the extension can be authenticated independently of the browser session.

Extension flow

Open the web app from the popup, sign in, generate a token, return to the extension, paste it once, and the extension remains authenticated until you revoke it.
