RatePunk alternatives
Free extensions that compare hotel prices on the page.
Updated November 8, 2026: Underbook is a free alternative to RatePunk that shows, on the hotel page you are viewing, the price each booking site Google Hotels lists for your dates (a median of 17 per hotel in our data), and says whether a lower price names the same room. It installs on Chrome, Edge and Firefox with no account. RatePunk, also free, adds cashback in its own coins and a check of other countries' prices, and its home page now leads with flight prices. Directo and Hotel Ninja are the other free extensions in this group.
This page is by Underbook, one of the extensions compared. Facts about the others come from their own sites and store listings, read November 8, 2026; they can change, and a correction to hi@underbook.co is welcome.

RatePunk: ratepunk.com, ratepunk.com/extension and its Chrome Web Store listing, and its Firefox Add-ons listing (about 1,500 daily users, 8 ratings, updated January 7, 2025), read November 8, 2026. Underbook: how Underbook works and its store listings. The median of 17 sites and the share with taxes reported are from our snapshots of September 25 to October 1, 2026 (5,830 hotels).
When RatePunk may be enough
If you want cashback in its coins, a check of what other countries are charged, help with Airbnb stays or a Safari extension, RatePunk says it does those, free. Underbook is the one to try if you want every site Google Hotels lists for your stay, small sites and the hotel's own site included, or want to be told whether a lower price names the same room. Both can email you when a refundable stay drops after you book.

What to look for in any of them
Three things from our hotel price study (7,044 hotel prices in 368 cities, 17 snapshots) that decide whether a price comparison is worth trusting:
- Which sites it checks. Some site listed the stay 5% or more below the going rate at 5,114 of 7,044 hotels (73%), and the lowest of those listings was on Booking.com, Expedia, Hotels.com, Priceline or Agoda at only 641 of 5,114 (12.5%). Most lower prices sit on smaller sites, so the number of sites checked matters.
- What it says about the room. At 4,294 of 5,114 hotels (84%) with a lower listing, the lowest named no room at all. A tool can only match a room the listing names, so look for one that tells you when it cannot.
- Taxes. At 2,542 of 3,371 hotels (75%) where taxes added 10% or more (snapshots of September 25 to October 1, 2026), the listings mixed before-tax and all-in prices, and at each of those the lowest listing was a before-tax price. Compare all-in totals, or know which you are seeing.
