ALTERNATIVE
A Mattermost alternative with meetings, docs and tasks included
Mattermost is open-source team chat you can self-host. Here is when Dock is a better fit and when it is not.
Why teams look for a Mattermost alternative
Wanting more than chat
Meetings, docs and tasks in one place.
Simplicity
Fewer moving parts to run.
Cost clarity
No per-seat licence to forecast.
What Dock adds
Meetings in the same app
Video calls with recording, transcripts and AI summaries.
Docs, tables, tasks and calendar
Not just chat.
AI agents
An MCP server so Claude Code and others can read and post in channels.
Simple to run
One Node process and one SQLite file.
What to check first
Mattermost has a larger integration list and mature enterprise controls such as SSO. Dock does not have SAML SSO today. If you need those, check Mattermost's current editions first.
Questions
Is Dock a drop-in replacement for Mattermost?
No. Check the feature list for the integrations and admin controls you rely on.
What does Dock cost?
No per-seat licence; you pay for your own server.
Can I run both?
Yes. Pilot Dock with one team before deciding.
