(the same measurement rule as awesome-made-by-russians )

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:

• The project was created by the developers born in Brazil
• The project can't be just an experimental or sample project
• The project has more that 100 stars on Github
• If they do, feel free to make a PR! 😁
