Matrix (Synapse) vs Rocket.Chat
Self-host pick — both replace Microsoft Teams (Team chat + video meetings).
Both Matrix (Synapse) and Rocket.Chat self-host as a replacement for Microsoft Teams (Team chat + video meetings). Pick Rocket.Chat if you want the lighter footprint — 20min docker-compose (Node + MongoDB), $10/mo vps; mongodb needs ram and growing index space. Pick Matrix (Synapse) if you need privacy-first or regulated orgs that want federation, end-to-end encryption by default, and zero-trust topology — 1h docker-compose (Synapse + Postgres + Element web client + TURN server for calls) and $15-30/mo vps; turn bandwidth dominates if calls are heavy.

Good fit for
Matrix (Synapse)
Privacy-first or regulated orgs that want federation, end-to-end encryption by default, and zero-trust topology.
Weak at:Operational complexity is the highest of the three — multiple components and a steeper learning curve.
Rocket.Chat
Customer-facing scenarios (livechat plugin), regulated environments (on-prem with SSO + audit trail), and orgs that need omnichannel chat with email/WhatsApp gateways.
Weak at:MongoDB ops surface — backups and upgrades are more involved than Mattermost's Postgres.
