I used Slack over the last few months and it’s an amazing tool for the teamwork but it’s closed and not self-hosted. http://www.mattermost.org/ is a great alternative, some interesting features:
It’s not a project management app at all but a messaging app for team as chat and realtime communication replacement
We believe that 1) internal messaging–across PCs and phones, with file sharing, archiving and search–is a vital layer of IT in a “post-email” world, 2) the platform for internal messaging needs to be open, and 3) that we wanted Mattermost to be the leading project to serve as the open layer for internal communications.
I think these are the vital options that distinguish this tool from other tools (including jabber/hangouts). I think that archiving and sharing through the application is very important to be able to create a transparent community.
Are you kidding? I totally agree with you.
Ask to @jaapvdv! We might start from the docker module following a centos howto. May it be the correct way to tackle mattermost?
I really prefer a solution where I can ‘limit the number of eggs in a basket’. So my choice has been to go for a separate ‘one trick pony’ VM with Mattermost. It would be really great to have Mattermost added to the arsenal of NS.
