Top IT Service Providers for JavaScript in Poland

134 IT service providers ranked by rating, review volume and listing quality.

JavaScript spans more ground than any other language on this list. It runs in every browser, on servers through Node, and inside mobile and desktop applications, so a firm listing it may be doing front-end interface work, back-end services, or both.

The useful clarification is which part of the stack, and with what. Front-end work is dominated by a handful of frameworks and the choice affects hiring for years afterwards. Back-end JavaScript competes with other server languages and is chosen for good reasons and bad ones. Ask why they would pick it for your project specifically — a clear answer indicates a team choosing tools, and a vague one indicates a team using whatever they already know.

Between them, the 134 IT service providers on this page cover web development (127), mobile app development (100), android (94) and iOS app (91). 132 of them have written a profile you can read before you get in touch.

We list more than 100 IT service providers in Poland listed for JavaScript development. The order comes from what each firm publishes and what has been verified about it, never from payment — at the top right now: BitBag, Ivision.pl and sunscrapers.

How is this ranking worked out?

The order comes from what each firm publishes and what has been verified about it, and never from payment:

Profile completeness: the details a buyer needs to judge a firm — what it does, who it serves, how it prices, who it has worked for
Earned trust: verification, awards and the other checks a firm has actually passed
Client reviews, where they exist: the rating is smoothed, so one five-star review cannot outrank a firm with a hundred good ones, and volume counts with diminishing returns

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 Poland are counted here, so a firm that lists a town but no country is not yet included.

Where else can I look?

The same list elsewhere: USA (762) · UK (478) · India (392) · Germany (214).

Other specialisms in Poland: e-commerce (311) · UI/UX design (259) · Android app development (249) · iOS app development (232) · PHP development (159).
