Deep Dive: Switching from Pumble to Mattermost Team Edition
Trade-offs, installation & data architecture
What you trade away
Mattermost Team Edition is a fuller self-hosted chat, but PostgreSQL, TLS, SMTP, storage, backups, upgrades, and uptime become the team's responsibility.
How to deploy Mattermost Team Edition
Install the official Linux binary with PostgreSQL, then configure systemd, TLS/reverse proxy, SMTP, and file storage
What it takes to run
The first obstacle is a real Linux service deployment, PostgreSQL, SMTP, DNS/TLS, storage, backups, and upgrades, not an app-store install.
Where your data lives
Channels, posts, users, and configuration live in PostgreSQL; file attachments live in the Mattermost data directory or configured S3-compatible object storage.
Why fork Mattermost Team Edition instead of vibe-coding a Pumble clone?
The core loop is buildable, but a dependable replacement becomes a real weekend or multi-day project. For Pumble, run straightforward team channels, direct messages, threads, and file sharing. The hard boundary is cross-platform apps, push, guest access, admin controls, and hosted reliability, plus network, moderation, and communication infrastructure.
