- Each has a real cost: Duetto nothing is published on price, and deals are typically annual per property licences on multi-year terms, so the real commitment is only visible after several sales meetings.; 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.
- They diverge on capability: Duetto covers Open pricing, Kayak covers Flight, hotel and car comparison.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Duetto
- Nothing is published on price, and deals are typically annual per property licences on multi-year terms, so the real commitment is only visible after several sales meetings.
- Implementation is a project involving data cleansing, PMS integration and configuration, and properties routinely take months to reach useful output, during which the licence is already being paid.
- The system requires a trained revenue manager to interpret and act on recommendations; a hotel without that function will not get value and would be better served by a rules-based tool.
- Value depends on clean historical and segmentation data from the PMS, and properties with inconsistent rate coding or short history get weaker forecasts with no easy remedy.
- It is priced and scoped for upper-midscale and above, so independent hotels under about a hundred rooms are typically outside the economic range regardless of how sophisticated their pricing needs are.
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.

Answered from the vendors’ own pages
Duetto: How much does Duetto cost?
Not published. Expect a per property annual licence scaled by room count, plus implementation, on a multi-year contract.
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.
Duetto: What is open pricing?
Yielding each segment, channel and room type independently rather than moving one best available rate and deriving everything else from it.
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.
Duetto: Is it worth it for a small independent hotel?
Usually not. Below roughly a hundred rooms, and without a dedicated revenue manager, a simpler rules-based pricing tool is a better fit.
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.
Duetto: How long does implementation take?
Months rather than weeks, driven mostly by PMS data quality and rate code cleanup.
