Mattermost / capabilities
What it covers
Channel structure, mobile apps, LDAP/SSO and integrations — set up so the team actually uses it.
Calls and screen
Voice and video calls, screen sharing — from the browser or the app.
Mobile apps
iOS and Android — with push notifications, so a channel never slips away.
LDAP and SSO
One account for every service — adding a new employee to one group makes them appear everywhere.
Integrations
Webhooks, bots and CI/CD notifications — the channel becomes part of the system.
Archive and compliance
Conversations stay with you — for audits, legal requests or simply history.
process
How the process runs
-
01
Structure
Which channels the team needs and what stays private — too many channels create noise.
-
02
Deploy
Mattermost via Docker, PostgreSQL, HTTPS and backups.
-
03
Migration
Importing history from Slack or Telegram where possible.
-
04
Training
Short rules: where we write, how we search and when we call — the team adapts quickly.
cases
Examples
From Slack to an own server
Channel structure, part of the history and mobile apps — the team moved in one day.
A support channel
Uptime Kuma alerts straight into a channel — the incident is resolved inside the chat.
Integration
Chat as the nervous system
Mattermost becomes most useful when the systems speak inside it.
faq
Common questions
Will Slack files migrate?
Text history and files migrate partially — depending on the Slack export format. I assess it beforehand.
How many resources does it need?
For 20–50 users, 2–4 vCPU and 4–8 GB RAM is enough. Files can live on separate storage.
