OS Apps: Antimatter
Some fun with OS Mattermost
I last looked at the OS version of Mattermost back in 2024 and over time people wanted a more open-source native fork. Antimatter forked from mattermost back in Sept of this year but is very active with 1338 commits since forking as of writing.
Let’s see what is new by firing this up locally with a local build…
Antimatter Let’s clone
