Mattermost is the open-source Slack alternative. Channels, threads, DMs, voice/video calls, file sharing, search — everything you expect from a chat platform, but on your own server. For businesses that don't want their communication routed through Atlanta or Dublin.
At Virtual Computing, Mattermost runs in a container with Postgres and optionally a Calls component (Jitsi-based). Messages are archived, searchable (including attachments via Tika), and compliant with retention policies you set — no secret Slack data disappearing after 90 days.
Mattermost is strong in compliance environments (government, defence, finance) thanks to audit logging, granular permissions and E2EE channels. But also fine for 'regular' SME teams that want to escape Slack's $7.25/user/month.
