Having been involved in the project in the last 3 years I've used a lot during this time.

Not only do I find it more intuitive to use by now (and github is slowly copying features that gitlab introduced years ago), it also really makes a difference that the development of gitlab itself is open.

Got an bug/feature request? Jump into the issue tracker and help shape the discussion about it. Or someone might even jump in and provide an implementation for it.

I finally have a solution for opening (libre/MS) office documents on my Phone using only free software!

With Nextcloud, Collabora Online and the Nextcloud Android app.

Editing should work too but is a bit buggy on my Phone still.
