yep - very similar but with an emphasis on self hosting.

Check out: https://zulip.org/ and https://zulip.org/features.html. The biggest difference from something like Slack is the threading model, which is documented in some detail on those pages.

Would nice if it were easier to self-host. Requiring Ubuntu 14.04 with 2GB RAM minimum...not terrible, but could point at a lot of work to be done to broaden the appeal. (Edit: And of course, a thank you to Dropbox for releasing it, this does look like a nice little setup)

Heh, in the days of VMs and containers that shouldn't be a problem. I'm sure there are already Docker containers and AWS images.

Zulip doesn't have a strong dependency on Ubuntu 14.04.

It would be less than a day's work to have it support any additional version of Debian or Ubuntu (precise/wheezy would be quite easy since we've run both in production). It's probably also not hard to support something RHEL-based too but that'd be a bit more work.

RAM usage could also be brought down a lot for smaller environments with a bit of work; most of it is the fact that we run a set of like 15 queue processing workers that each import the entire application.

Where would one start if they were looking to disable that?

Posting this in a few places since it came up N times on this thread: I opened https://github.com/zulip/zulip/issues/32 to track improving the worker setup.

If you're interested in helping I'm more than happy to give you a bunch of pointers for how to do it :)

Also open source (which means it can be extended / modified / etc).
