Not sure if someone mentioned it already but I also used bitbucket in the past and found it very easy to use with a similar offering as github.
GH beat them on UI/UX and the PR workflow I think. Really nothing more than having a better ~$120k Product Designer working there. Kinda funny what actually makes people stick with 1 choice over another. Very often it’s just having better UI/UX, or offering something useful for free.
I use it at work alongside GitHub (patchwork of merged companies).
There are random little things I like about it better than GitHub, especially in an enterprise setting.
And it has never gone down in my entire tenure at this company, while GitHub is like a weekly outage nightmare these days.
Atlassian is doing a whole lot of strange and desperate stuff lately including some pretty insane UI changes in Jira and their other products, but Bitbucket seems like it’s been neglected the exact right amount for it to be a pretty decent choice.
