FOSS projects built in India

Shameless self-promo: We at are a FOSS-only development agency that works on your FOSS dependencies. You simply forward an open issue in any open-source software and irrespective of the skills it takes, we will get it done. Think of us as the polyglot, open-source developer on your team. By working with multiple corporate customers, and having a pool of talented developers across skills, we can do this much more cost-effectively than you doing the same in-house. You only pay for what’s valuable to you.

It seems to be a widespread impression that Indian developers are mostly consumers, and not contributors, of FOSS. To dispel this myth, we are compiling a list of some of the best open-source software that were primarily built primarily by Indian developers. This is just a list, NOT a ranking. For any additions or modifications in this list, send a pull request.
