  1. fastapi

    FastAPI framework, high performance, easy to learn, fast to code, ready for production

    If you’re a developer, most likely you have encountered libraries, frameworks, or programming languages that are open source. In case you use packages from NPM in your projects, you can find on the package page the link to the project's source code. Take the example of the react-kawai package which points to the miukimiu/react-kawaii GitHub repository. Same works for Python packages from PyPI. Take as an example fastapi package that points to tiangolo/fastapi GitHub repository.

  4. flask-jwt-extended

  5. Zulip

    Zulip server and web application. Open-source team chat that helps teams stay productive and focused.

    Now, I want to highlight that you may use a project in another role other than as a developer. For example, if you are using an end-user application (using a real-time chat app, like Zulip, to communicate with other people). You can still find the project source code repository, and contribute in many ways.

  6. jogo-das-profissoes

    O Jogos das Profissões é um jogo da memória simples, interativo, inclusivo e educativo para toda a comunidade infantil e famílias.

  7. hire-me

    A path to getting an awesome tech gig 💼

    The way I got started with open source was via an initiative to incentivize people to contribute during December, 24 Pull Requests. I decided to make a first small contribution using Markdown, which you can check out at FrancesCoronel/hire-me/pull/9 on GitHub.

  8. PortugueseOpenSourceProjects

    List of Portuguese Open Source Projects and respective repositories

    Sometimes you might also find repositories that contain only informational content, and some, in particular, will have a compilation of projects. For projects in the Portuguese community, there’s a nice collection of Portuguese open source projects at the OldMetalmind/PortugueseOpenSourceProjects GitHub repository.
