I've never used Mattermost before today. After checking out their site, I can see they are also a for-profit company. What does Mattermost offer that Slack does not, other than a bill lower than $195K/year?

You can deploy it self-hosted without paying any fee, so you control your data much more.

  • Last time I checked they cripple the self-hosted version, asking to subscribe for enterprise plan here and there. Source: deployed their chat locally a couple of weekends ago. Overall, I liked their Slack clone, they this one was a red flag to me. Now I’m not sure we want to deploy this, but I know very little alternatives. Zulip, but it cripples its self-hosted version too. It allows just 10 mobile users (notifications). Maybe Matrix it is then, but it’s not very suitable for airgapped company-wide deployment.

      Element is literally built for airgapped company-wide deployments - this is precisely what https://element.io/server-suite is? It was originally built to install onto SIPRnet; it's been airgap-first since day 1.

    • Mattermost is AGPLv3. You can deploy the whole stack and own your data without paying a cent to Mattermost the company.

    • How are you expecting the devs to get paid with zero incentive for customers to do so?

Mattermost is open-core software: you can self-host and they can't turn you off or raise the price.
