The short version

  • Only Kayak has a free tier, so it costs nothing to try first.
  • Each has a real cost: Kayak it is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.; WebRezPro no pricing is published at all, so evaluating WebRezPro means a sales conversation before you can compare it against Cloudbeds or Little Hotelier on cost.
  • They diverge on capability: Kayak covers Flight, hotel and car comparison, WebRezPro covers Mixed inventory types.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Kayak

  • It is owned by Booking Holdings, the same parent as Booking.com and Priceline, so its comparison results are not fully independent of its own group's commercial interests.
  • Some airlines opt out of listing on metasearch sites entirely, so Kayak's results are not a complete view of every available fare in the market.
  • Revenue comes from referral commissions, and prominence in results can be influenced by which suppliers pay Kayak more, not purely by lowest price.
  • The actual booking typically completes on a third party site, so problems with a booking, cancellation or refund are handled by that site's customer service, not Kayak's.
  • Displayed prices can change or fail to match by the time a user reaches the booking site, since Kayak is not always querying live inventory in real time for every listed fare.

WebRezPro

  • No pricing is published at all, so evaluating WebRezPro means a sales conversation before you can compare it against Cloudbeds or Little Hotelier on cost.
  • The interface is dense and dated, and staff used to modern consumer software typically need structured training rather than picking it up on shift.
  • There is no meaningful native mobile app for staff, so housekeeping and maintenance workflows are done through a browser on a phone rather than a purpose-built app.
  • The third-party integration ecosystem is small, and requests for connections outside the existing list usually mean a custom development quote rather than a marketplace toggle.
  • Revenue management is limited to rate rules and yield triggers rather than genuine demand forecasting, so properties that want dynamic pricing need to add PriceLabs or RoomPriceGenie separately.

Answered from the vendors’ own pages

Kayak: Does Kayak charge a booking fee?

No, Kayak itself is free to use; it earns referral commissions from the airlines, hotels and sites it sends bookings to.

WebRezPro: How much does WebRezPro cost?

It is quoted, not published. The model is per unit per month with a monthly minimum, and the per-unit rate differs for hotel rooms, hostel beds and campsites.

Kayak: Do I book directly through Kayak?

Usually the booking completes on the airline, hotel or travel site's own platform after Kayak hands off the click, though some direct booking options exist for select content.

WebRezPro: Does it charge commission on direct bookings?

No. The booking engine is commission-free; you pay the subscription and your own card processing rates.

Kayak: Is Kayak owned by an airline or hotel chain?

No, it is owned by Booking Holdings, which also owns Booking.com, Priceline and Agoda.

WebRezPro: Can it run a campground and a hotel together?

Yes. Mixed inventory in one property is one of the reasons operators choose it over a rooms-only PMS.

WebRezPro: Is there an open API?

There is an API for partner integrations, but it is not self-service in the way Mews or Apaleo publish theirs, and access is arranged through the vendor.
