We're using enterprise git and travisCI at my work and it's been great to use. I prefer build configs in the project, travis does that very well and the flexibility it offers us in how we approach our pipelines has been awesome.
edit: props to TravisCI support, we've had a few late nights do to different issues and they are responsive and very much engaged with their customers.
Hopefully I can free up some time this year to explore some other ones; gitlab is awesome but until they fix their performance issues (idk, maybe they did it's been a few years) it's a huge no go for me.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
