Where each falls short
The honest trade-offs — what you give up with each, versus the proprietary tools they replace.
Jam
- No persistent channels, history, or message storage
- No authentication or access control by default
- Limited scalability beyond small groups without custom TURN/SFU configuration
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.
Bottom line
Choose Jam if you want the lower-effort setup; choose Novu for the larger community and ecosystem. Novu has seen more recent development. Open each guide below for deploy steps and the full feature gap.
