Overall Satisfaction with Mattermost

Mattermost is used company-wide as a collaboration tool, providing chat and conferencing options


  • Slack-like collaboration
  • A wide variety of plugins


  • Somewhat random selection of features that require a paid version
  • The usefulness of some integrations is questionable
  • It has allowed us to implement videoconferencing between our offices very simply and cheaply.
  • Some non-technical users have expressed frustration with trying to use more complex features, requiring more IT intervention.
We have not modified the code
The integration options can be less than intuitive
Mattermost is very similar to Slack and has the advantage (in our case) of being entirely on-premises, and entirely free. The feature set is similar, and it has filled the original need that Slack was suggested as a solution for very well. Teams is potentially a better choice for groups whose Microsoft licensing already includes it, or who want the range of direct integration with other Microsoft products.

Did implementation of Mattermost go as expected?


Would you buy Mattermost again?


Mattermost is perfect for teams that want to take advantage of what Slack offers without incurring the cost or opening up the security risks of a cloud-based collaboration platform. It is perhaps less than ideal for users who are very non-technical or who want a lot of features in a plug-and-play package.
