I will always be a bit entertained by how gitlab is a (relatively) big bulky installation that affects a bunch of stuff and takes up a bunch of resources. My pi 2 had some troubles with it with more than one person. then gitea is like 'the executable is less than 100mb, requires no external dependencies and it take about 30mb of ram if you have 2 or 3 people using it'
I get that gitlab is made for a much larger workload, but the difference in complexity is amusing.
Someone makes a huge complex piece of software and tries to sell administration and maintenance as a service, then someone else comes along and is like 'or you could do it in this really simple way that requires almost no resources'.
Not that I don't like gitlab, they are rather important in the alternative to GitHub sense, but you are going to have maybe 100 organisations in the world that need something that can support the type of traffic required to justify something that complex.
