Surprisingly GitLab feels very dated. Their drive has been toward enterprise sales instead of product IMO. Nothing bad about that - but focus on product development at least as well.
We've also invested heavily in AI features including Code Suggestions which is free for all users while in beta. You can read more about the AI features in GitLab here: https://about.gitlab.com/solutions/ai/
It's UI infuriates me quite frequently, options, menus, projects all the useful things are hidden behind UI elements which requires to click constantly to reveal items. All of that while plenty of unused blank space is available on the screen, fucking dumb.
