But if a UI works and is not copyrighted? I am against a scarcity mindset where we have to reinvent the wheel. Naoki has saved time and spent it more productively on the codebase and then released it as an OS product, good.
I know there are other solutions like Gitlab, but from what people are saying here, it is harder to setup & maintain, so I do not feel that this particular product does not bring something new.
Maybe create an open source GitHub/Bitbucket UI that people can use in their projects?
