Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Novu
- Not a real-time team chat; it is a notification delivery layer, not a conversation platform.
- Self-hosted setup requires Postgres, MongoDB, Redis, and S3-compatible storage, adding operational burden.
- Managed cloud features (advanced analytics, SLA guarantees) are not available in the open-source edition.
- Mobile SDK for in-app notifications has fewer features than commercial equivalents like OneSignal.
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. Open each guide below for deploy steps and the full feature gap.
