Where each falls short

The honest trade-offs — what you give up with each, versus the proprietary tools they replace.

Rocket.Chat
  • Resource-heavy (Node.js + MongoDB) and can be slow at scale on modest hardware
  • Some enterprise features (engagement dashboard, scalability, advanced auth) require a paid plan
  • UI can feel cluttered compared to Slack
  • Mobile apps have historically lagged the web client in polish
Stalwart XMPP
  • Younger project with a smaller community and less battle-tested than Prosody or Ejabberd
  • No native web chat client included; users need a third-party XMPP app
  • Clustering and high-availability support is still maturing

Bottom line

Choose Stalwart XMPP if you want the lower-effort setup; choose Rocket.Chat for the larger community and ecosystem. Rocket.Chat has seen more recent development. Open each guide below for deploy steps and the full feature gap.
