I've been working on migrating to using phabricator at my company. The developer workflow is a bit different than that of GitHub/GitLab but it's nothing that should hinder development. Primarily it revolves around using a client-side command/utility called 'arcanist' in order to submit code for reviews. The largest difficulty is working with feature branches which is a newer concept at my company.

I have it working with LDAP + ssh access (a la GitHub, everyone uses the 'git' account to push but uses their own keypair for authentication). The review system works quite well, and one thing that I hadn't seen in other systems is the ability to "squash" revisions -> while the code is being reviewed and updated, once it's finally 'landed' into the repository all the diffs can be squished to a single commit rather than having multiple commits correcting eachother. One of the nicer things about running Phabricator is that it has quite a bit of documentation, and

I've been quite pleased with Phabricator, and the bright people working on it are always helpful in the IRC.

The largest gripe I have with Phabricator is the UI is a little tedious at times (multiple page navigations for doing some things which feel like it could be simpler, etc.).

You can create yourself an account on their hosted version, and browse their development of Phabricator: https://secure.phabricator.com/

Edit: One other thing I wanted to point out which Phabricator does that GitHub/GitLab and others do not appear to - Phabricator starts to form a model around "Ownership" of code which has been useful on a large project. People can elect to be notified when areas of code change that they otherwise would not notice.

I realized I left a dangling sentence:

..and the install provides really great feedback about how it's running. Server issues are identified and displayed to logged-in administrators, so phabricator actively analyses its status and any reports what actions might need taken. The upgrade process is really smooth as well.

Thanks (to you and the others) for your replies. The code ownership thing is interesting, I saw something similar in Zach Holman's presentation on how GitHub works: http://zachholman.com/talk/move-fast-break-nothing/

We switched to it 6 months ago and are loving it. We have about 20 developers interacting with it and recently people are starting to move more and more project management and analysis tasks in alongside the code stuff (engineering/modeling/design company).

Arcanist - command line tool, great! GUI - confusing, strange names on modules and lots of navigation issues. Tasks - works, but too clumsy Workboards - just too bare bone to be functional code review - one of the better ones

We use gitlab as a replacement for gitosis and in that workflow there is no longer any room for phabricator.

But now that phabricator can self host repos it is a big plus. They should rework the GUI, it is my biggest gripe at the moment.

What I miss in all tools I have tried is to make a random comment in the source tree. I don't want to fake a branch to achieve that.

Phabricator is a brilliant piece of software. Very well written code, an emphasis on security, nice UI, tons of features.

Once you get used to it, the Differential code review process feels very natural (better than pull requests, even).

I like it much much better than Gitlab, and find it's real good alternative for Atlassian's stack. I've been nothing but pleased with it and I've deployed it a number of places now. The biggest thing is that everything is integrated (i.e. it plays well together, unlike trying to graft Redmine + Gitlab or other combos), and that installation and upgrade is comparatively painless. The sense of humor is also an added plus.

What integration are you missing from GitLab? It has issue tracking, version control, code reviews, wiki's, CI and CD out of the box. Maybe we can use a little more of https://gitlab.com/gitlab-org/gitlab-ce/blob/master/CHANGELO...

I played with it a little bit once for a small personal project. It seems to have all the features you want, but the way you used them never really clicked with me.

Unlike Stash, GitLab, GitHub, Gogs, or others of that nature - though - it expects you to setup your git repositories elsewhere (at least the last time I used it) instead of acting as a receiving host for them (at least the last time I used it - which was a year or two ago at this point).

This has changed; we've supported hosted repositories since late 2013.

Phabricator does host git repositories. The workflow is a bit strange when compared to github's more natural PR model, but it works, and is overall quite solid.

Bonus points that in encourages you to upload memes under macros to troll your coworkers when doing code reviews.

I used it when I was contributing to Wikimedia in Google Code-In. It was very easy to use and the issue system was very powerful. The whole system looks powerful.
