CustomRates

See the discounts and perks your loyalty memberships actually unlock — right on the search page.

Booking.com shows everyone the same rate. It doesn't show you the cheaper one you can unlock in 30 seconds. CustomRates is a free overlay for hotel booking. While you compare hotels on Booking.com (or Hotels.com, Expedia, Trivago), it shows you — right there on the results page — which of those exact hotels give you a bigger discount when you book direct with a "free-to-join" membership. That's the part the anonymous web hides. Tons of hotels run a "register and save" rate: join their loyalty club for free — no status, no fee, no waiting — and the direct price drops 5–20%, often with free breakfast, a room upgrade, or late checkout on top. You were never going to spot that while scrolling an OTA. CustomRates surfaces it the moment you look at the hotel: the discount %, the perks, and a one-click link to book direct and actually claim it. Sure, it's great to see every hotel in one place on Booking.com. It's even better to see, right then and there, how much less you'd pay by booking that same hotel directly and using a membership anyone can get for free. WHAT YOU SEE • "Members save 15% — book direct" badges on the hotels you're already browsing. • Free-to-join deals anyone can claim today — no elite status, no prior stays, not even a CustomRates account. • The perks that come with them: free breakfast, room upgrades, late checkout, welcome extras. • A direct link to the hotel's own booking page, where the discount is actually applied. • Your own memberships too (Booking Genius, Accor, IHG and more) once you add them — everything you're owed, in one place. WHY IT'S DIFFERENT • It finds the free membership you didn't know the hotel had — the "available to everyone, just sign up" discount, not some elite tier you'll never reach. • No price games. It shows the discount and where to claim it; you (or the hotel's own page) see the final number. If a discount is already baked into the page (like Booking Genius), it says so instead of double-counting. • It's your vault, not an ad network. No injected affiliate links, no rewritten checkout, no reading your logged-in sessions. Free forever for travelers. HOW TO START (30 seconds) 1. Install CustomRates. 2. Browse hotels on Booking.com, Hotels.com, Expedia or Trivago as usual. 3. Watch the free-to-join deals appear — then book direct and save. (Optionally add your own memberships for even more.) BONUS — works with your AI assistant too: connect the free CustomRates MCP server to Claude, and "find me a hotel in Prague" comes back already knowing which ones you can save at. Your memberships are yours. Credentials are encrypted, we never read your logged-in sessions, and we never sell your data.
