I heard about Phabricator from Greg, in reference to the WMF collapsing a bunch of other tools into this one omni-developer app. I've been struggling to figure out what I am doing with my repo hosting, so it was neat to hear a large org moving to something that is free software and self-hosted.
I've spent about a week with it, and I've been up and down, most so than with any other software I've ever used. I didn't quite understand why I was hung on this software so much, but for the last few days it has been all I can think about. I am starting to break it down, now.
First thing: I wish I had found Phabricator when I was first starting out, maybe back in the cog motive days. It does a lot of stuff really great, and outside of an org that does shared development, it has some great features for single freelancers, like the simple interface for creating and signing contracts.
It bums me out that it doesn't hit all my needs, but it did make me reassess what my needs were. The git hosting doesn't come close to Gitorious or GitLab, but those are specialized apps, and they only have light issue-tracking on top of it. I am actually quite fond of the tasks in Phabricator, but tracking issues around code outside the repo is not what I'm looking for.
Basically, I want Phabricator to scale! I want big, huge, public instances of it, but that isn't the tool they made, though it can organize large groups of folks. I think it is the perfect tool for WMF, which will have a relatively narrow focus. I want a single todo list, and I won't be able to get it from Phabricator.
However, my own personal work is taking me in interesting directions lately, where I am focusing on fewer clients, but larger projects. I can already think of 2.5 new instances that I should be running, and they do not overlap. And for other projects, I think I have some WordPress plugins that make more sense, since they are less technical in detail, and allow for a conversation to develop with folks that may not want an account to a complete organization system.
