I forgot about Phabricator until recently. It certainly has a particular attitude that might be helpful for a medium-sized team I’m on.
Phabricator is a suite of web applications that help software companies communicate about software effectively. It was created at Facebook. Phabricator is also used at many other companies such as Airtime, Asana, Dropbox, deviantART, MemSQL, Path, Quora, and more.
