This web app uses the GitHub API and GitLab API to fetch, process and nicely display the projects/repositories of any subscribed cooperative from over the world.
Please note that it’s strictly limited to cooperative enterprises.
The main goal is to gather in one place all the open source projects that can be used to start others, to be consumed, to learn or to just motivate collaboration.
