Was Gitlab around?
2008: Github launched
2008: Bitbucket launched
2010: Atlassian purchases bitbucket, makes private repos free
2011: Gitlab launched
2014: Gogs (Gitea's predecessor) first public release
2016: Gitea forks from Gogs
So at the very least, bitbucket was established and gitlab was around
I don’t even know why. Just seeing the interface rubs me entirely the wrong way.
Indeed fossil-scm [1], has same interface as Trac (in my view partly inspired by it). Have used Trac for a long time, so can't complain, it works well, its simple and flexible.
