Use Cases and Deployment Scope

We used Mattermost for a few months as our corporate chat tool to enable cross-regional discussions about work matters.

Pros and Cons

Self-hosted option
Many features on-par with Slack, such as public and private rooms
Open API supporting integrations with many services

UI glitches were frequent occurrences
Base pricing is competitive with Slack, but enterprise features come at a hefty price
Webhooks are cumbersome to set up compared to Slack

Return on Investment

Self-hosted security
Additional IT installation time
Additional internal security reviews for managing self-hosted firewall rules

Usability

Some UI glitches, and often lackluster performance when switching between channels.

Support Rating

Usually we were directed to the forum to file enhancement requests for things that were basic features in Slack

Mattermost may be most useful in a highly-regulated environment where self-hosting a chat solution is essential. But many cloud providers now offer HIPPA/FIPS-compliant chat solutions so it may no longer be necessary to self-host your own chat solution. Recommend doing your own research to be sure you aren't investing prematurely in a self-hosted option.

A worthy consideration as a self-hosted Slack solution, with some caveats
