The order comes from what each firm publishes and what has been verified about it, and never from payment:
Client reviews are still rare across this catalogue, so on most lists today the order is set by the first two. A firm near the top is the best-documented and best-verified one we hold, which is not the same claim as the best one to hire. Use the list to build a shortlist, then check the firms yourself.
Sponsored listings are labelled and shown apart from this list. How rankings work
Only firms whose profile names Ukraine are counted here, so a firm that lists a town but no country is not yet included.
The same list elsewhere: USA (510) · UK (363) · India (334) · Germany (182).
Other specialisms in Ukraine: e-commerce (262) · UI/UX design (258) · Android app development (245) · iOS app development (234) · PHP development (191).
Every IT service provider in Ukraine: the full list.
Every category in Ukraine: the Ukraine country page.
Every other way we rank it service providers, by what they do and where they are.
