Same here, really great as it packs a lot. The new Gitlab 8 with the CI integrated is great as well but we preferred Phabricator for the extended feature.

Ultimately we decided not to embrace fully yet the Phabricator CI (harbormaster/drydock) as it's been changing a lot (it's a prototype after all) and breaking frequently so we have a mix of Harbormaster and Jenkins which works very well.

The main thing that's confusing me about Phabricator is that it seems to be centered around a one-repository workflow (which I gather FB uses). Does it work well when you have different projects that are unrelated to each other, or is the idea to set up dedicated instances for each project?
