Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Dendrite
- Still behind Synapse in feature completeness for some advanced room types
- Performance at scale is less battle-tested than Synapse
- Web client (Element) must be deployed separately
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
Bottom line
Both are a similar lift to self-host; 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.
