The short version

  • Each has a real cost: Didi uber does not operate ride hailing directly inside mainland China as a result of the 2016 acquisition deal, so travellers used to Uber have no equivalent option there and must use Didi or another local operator instead.; 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: Didi covers Ride hailing, Kayak covers Flight, hotel and car comparison.
  • 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.

Didi

  • Uber does not operate ride hailing directly inside mainland China as a result of the 2016 acquisition deal, so travellers used to Uber have no equivalent option there and must use Didi or another local operator instead.
  • Didi faced a major Chinese cybersecurity review and app store removal in 2021 following its US stock listing, related to data handling concerns, which is a relevant fact for anyone assessing how the platform manages user data under Chinese regulatory oversight.
  • The international-market apps in countries like Brazil and Mexico are separate products from the dominant China platform, and feature parity, support quality and market position differ meaningfully between them.
  • Payment methods within China rely heavily on WeChat Pay and Alipay integration, which can be a barrier for foreign visitors without a linked Chinese payment account.
  • As with the rest of the ride hailing category, fares are dynamic with demand-based surge and no published flat rate card, making advance cost estimation difficult during peak periods.

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

Didi: Does Uber operate in China?

No, not directly. Uber sold its China operations to Didi in 2016 in exchange for an equity stake in Didi, and does not run ride hailing directly inside mainland China as a result.

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.

Didi: Where does Didi operate outside China?

In a smaller set of international markets including Brazil and Mexico, where it competes directly against Uber rather than holding the dominant position it has domestically.

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.

Didi: What happened with the 2021 regulatory issue?

Chinese regulators conducted a cybersecurity review of Didi shortly after its US stock listing, related to data handling concerns, resulting in an app store removal and later fines; the app was reinstated to domestic stores after remediation.

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.
