Get the extension

The CapFare extension for Chrome (and other Chromium browsers) reads the flight on a booking page and shows what it costs to lock a maximum price. Testnet prototype: no real money.

Install

  1. Download the extension (.zip) and unzip it. This build talks to this CapFare demo and checks the demo booking site automatically.
  2. Open chrome://extensions and switch on Developer mode (top right).
  3. Press Load unpacked and choose the capfare-extension folder.
  4. Pin CapFare from the puzzle-piece menu so its icon stays in the toolbar.

Try it

Open Skyline Travel, the demo booking site

  • Search a flight (for example Amsterdam to Barcelona): CapFare offers a Price Cap on the results.
  • Book with any test card number such as 4242 4242 4242 4242. Nothing is charged; the confirmation email lands in the site's demo inbox.
  • On the confirmation page CapFare offers a Drop Guarantee; on the manage-booking page, Verify with CapFare checks the booking for a claim.
  • On any other site, press the CapFare icon and Check this page, or switch on automatic checks there. On testnet, prices come from the demo price source, so offers appear for demo routes.
