JetBrains

JetBrains ranks 21st overall in the developer tools category with a composite score of 65 out of 100. The organization describes itself as JetBrains Open Source, which frames how developers first encounter the brand on GitHub, in package registries and in search results.

Its shipping velocity and documentation and learning material come across as strong, and are what most developers will notice first when they land on the organization. By contrast, its developer experience and AI and agent readiness look minimal today, which is the clearest area where a small amount of focused work would visibly move the needle. Taken together, the picture is of a company whose public developer surface is neither uniformly polished nor uniformly weak, and where different audiences (contributors, integrators, evaluators) will likely form very different first impressions depending on which door they walk through.

JetBrains maintains 841 public repositories on GitHub, built primarily in Kotlin, Java and Shell, which together have collected 200,377 stars and drawn contributions from 196 developers outside the core team, 75 of those repositories have seen commits in the last 90 days, a useful proxy for how much of the codebase is genuinely alive rather than archived.

For anyone evaluating JetBrains as a technology choice, weighing a contribution, integrating the APIs, or comparing it against similar companies in the space, the sections below break down each of these signals in detail and link straight through to the underlying repositories, documentation and community threads that inform the score.
