@hakanohi Gitlab.com is hosted at Google Cloud. And while they have an open source community version of Gitlab, a large part of Gitlab is "enterprise" and proprietary software.
I would advise you to consider something's that's libre software like Gitea. It's self-hosted, but there's at least two popular non-profit websites who offers free hosting.
NixNet is run by @amolith.
* https://codeberg.org/ is another gitea instance (iirc)
* https://sr.ht/ is @sir 's take on collabotive work (not just coding) which is more email-centered (I may not be fully doing it justice, here, I know if it's existence but lack the personal experience with it)
@hund @hakanohi Or you can make a pragmatic decision and use Gitlab. 1) It's the biggest competitor to github with a lot of large foss projects and more coming. 2) All the most necessary features are open. 3) Once disaster strikes and you have to migrate your project all your Issues and other project stuff will be compatible with Gitlab CE and easily migrated.
Fosstodon is an English speaking Mastodon instance that is open to anyone who is interested in technology; particularly free & open source software.
