Codeberg is a public non-profit Forgejo instance hosted by the actual maintainers of the tool. They’re compromised with free software and provide their services with no pay walls other than a single limitaiton: only accepting open-source projects in their instance. That shouldn’t be a problem if you want to work on open-source, right?
A new pilot will investigate the use of Forgejo (A non profit FOSS alternative to github and gitea) in german schools (blog.codeberg.org)
