• The place for your next great pet project!

A lot of developers in Russia do not know about these projects and the fact that their authors are also Russian programmers. It warms your heart when you understand that a lot of highly popular and useful projects are made by “cold and gloomy” Russians.

This tweet by @fobbyal:

Is there a cool open source project mainly contributed by Russian developers?

...triggered us to create this repo.

The goal of the project is to show how modern software is a product of global culture. There are many different nations in your package-lock.json, or Gemfile.lock, or elsewhere. And we are highlighting the Russian part just because we know it better (#2).

It's hard to calculate project popularity so we use stars as a measurement. It's not quite fair, but it is what we have here on Github.

If you want to add project to this list, please, make sure that:

1. The project was created by the developer born in Russia or self-indicate themself as Russian.
2. The project has more that 1000 stars on Github.

If they do, feel free to make a PR!

(Please, check twice that you have picked the correct category and added the project according to alphabetical order.)
