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.; Regiondo a per-ticket fee applies on top of the subscription, so a high-volume operator selling many low-price tickets pays disproportionately compared with one selling few expensive ones.
They diverge on capability: Kayak covers Flight, hotel and car comparison, Regiondo covers Booking widget.

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.

Regiondo

A per-ticket fee applies on top of the subscription, so a high-volume operator selling many low-price tickets pays disproportionately compared with one selling few expensive ones.
Regiondo now shares an owner with Rezdy and Checkfront, so evaluating the three against each other is evaluating one company presenting three faces.
It was owned from 2019 to 2023 by the parent of Jochen Schweizer and mydays, an experience reseller, and operators who signed during that period were running their bookings through a system owned by a distribution competitor.
Strength is concentrated in German-speaking Europe; OTA depth, language coverage and support quality drop noticeably for operators in other regions.
The product is deliberately simple, and operations with complex shared-resource constraints across many products find the scheduling model too coarse.

Answered from the vendors’ own pages

Kayak: Does Kayak charge a booking fee?

From about 59 euros a month for Grow and 99 euros for the higher tier, with a small per-ticket fee on confirmed bookings and 10 per cent off for annual payment.

Kayak: Do I book directly through Kayak?

Regiondo: Who owns Regiondo?

Expedition Software Holding, backed by Vertica Capital Partners, since 2023. Before that it was owned by ProSiebenSat.1 within the Jochen Schweizer mydays group.

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

Regiondo: Does it charge commission on my own website bookings?

Regiondo: Is it a good fit outside Germany?

It works, but the OTA connections, payment methods and support are built around German-speaking Europe first.
