@sam, there is also #SourceHut, which has some of the best CI experience out there with SSH'ing into builds and stand-alone builds. It does/will require a paid account though ($20 a year to $10 a month) but that's only necessary for hosting. The ecosystem is built around #email, so contributors need not have an account and users from different instances can easily send patches to each other (yay federation!).
