HotelPriceTracker is a free, browser-based tool that tracks hotel prices on Booking.com, shows price history charts, and sends real-time email alerts when rates drop. Hopper is a mobile app that uses AI to predict future hotel prices and recommends whether to book now or wait. HotelPriceTracker gives you raw data and control over your rebooking decisions; Hopper gives you AI predictions and a curated mobile booking experience.

HotelPriceTracker is purpose-built for travelers who already know which hotel they want and need a reliable way to monitor its price. Paste any Booking.com hotel URL, choose your dates, and the tool begins checking rates around the clock. When the price drops, you get an email alert so you can rebook at the lower rate — no app download required.
Unlike prediction tools, HotelPriceTracker shows you actual historical pricing so you can judge for yourself whether today's rate is high or low. The calendar view lets you spot the cheapest check-in dates at a glance. Because you book directly through Booking.com, you keep your loyalty points and preferred payment method. The service is completely free — there are no commissions, no premium tiers that gate alerts, and no required account for basic tracking.
Hopper is a travel booking app that uses machine-learning models trained on billions of price data points to predict where hotel (and flight) prices are headed. Its signature feature is a color-coded recommendation — green means book now, yellow means watch and wait, red means prices are rising fast. The app also offers optional add-ons such as price freeze (lock in a rate for a fee) and cancel for any reason protection.
Hopper is a mobile-only experience. It operates its own hotel inventory and does not integrate with Booking.com listings, so you cannot use it to track a specific hotel you found elsewhere. It is best suited for travelers who are still deciding where to stay and want algorithmic guidance on timing their purchase.
HotelPriceTracker is better if you want transparent price history charts, free monitoring without booking through the app, and full Booking.com support. Hopper is better if you prefer AI price predictions and a mobile-first booking experience. They serve different use cases rather than one being strictly superior.
Hopper is free to download and use. It earns revenue through commissions on bookings made through the app and optional add-ons like price freeze and cancellation protection. HotelPriceTracker is also completely free with no booking commission required.
No. Hopper uses its own hotel inventory and does not support tracking hotels listed on Booking.com. HotelPriceTracker is specifically built for Booking.com and lets you paste any Booking.com hotel link to start tracking immediately.
HotelPriceTracker provides price history charts so you can see how a hotel's rate has changed over time. Hopper focuses on forward-looking AI predictions (buy vs wait recommendations) rather than historical price data.
Hopper is a mobile-only app available on iOS and Android. It does not offer a full desktop or web interface. HotelPriceTracker works entirely in the browser on desktop, tablet, and mobile devices.
No credit card required. Paste a Booking.com hotel link, set your dates, and get an email the moment the price drops.
