3 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 3 IT service providers on this page cover custom software development (2), software development (2) and web design (2). 3 of them have written a profile you can read before you get in touch.
We list more than 200 IT service providers in Germany 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: X1 Group, EdgeCase Technology GmbH and YND.

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 Germany are counted here, so a firm that lists a town but no country is not yet included.
The same list elsewhere: USA (762) · UK (478) · India (392) · Ukraine (145).
Other specialisms in Germany: e-commerce (553) · UI/UX design (422) · iOS app development (398) · Android app development (393) · PHP development (258).
