Most hotel price trackers make you manually enter booking details or use their platform to book. Rate Ranger is different: just forward your confirmation email. We automatically extract the hotel, dates, and price, then monitor rates across 30+ booking sites. Price drops? You get an alert with a direct link to rebook and save. No app to install, no accounts to create, no manual entry. Works with Booking.com, Expedia, Hotels.com, Agoda, Trip.com, and more.
