  • 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.; Rezdy rezdy, Checkfront and Regiondo have shared an owner since 2023, so an operator running a three-way comparison is choosing between products from one company with one roadmap.
  • They diverge on capability: Kayak covers Flight, hotel and car comparison, Rezdy covers Session and capacity management.
  • 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.

Rezdy

  • Rezdy, Checkfront and Regiondo have shared an owner since 2023, so an operator running a three-way comparison is choosing between products from one company with one roadmap.
  • Every tier carries a percentage booking fee on top of the subscription, so the cheapest plan is the most expensive per booking and the true cost rises with success rather than staying fixed.
  • The marketplace is the main reason to be there, and its reseller depth varies sharply by destination; in a market with few connected agents you are paying a distribution premium for nothing.
  • Setting up complex products with shared resources across sessions is fiddly, and operators regularly need vendor assistance rather than configuring it unaided.
  • Payment processing is layered on top of the booking fee, so the effective take on each reservation is materially higher than the advertised percentage suggests.

Rezdy: Who owns Rezdy?

Expedition Software Holding, backed by Vertica Capital Partners, which also owns Checkfront and Regiondo following a 2023 rollup.

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.

Rezdy: Does Rezdy charge on direct website bookings?

Yes. The booking fee applies to bookings processed through the platform, including those from your own site, on top of card processing.

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

Rezdy: What is the marketplace worth?

Rezdy: How much does it really cost per booking?

Add the tier booking fee, roughly 1.75 to 2 per cent, to your card processing rate, then add the monthly subscription spread across your volume.
