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.
Stoat
- Relatively new project; ecosystem of integrations and bots is minimal compared to Slack
- No voice or video calling built in
- Mobile apps not yet as mature as established competitors
- Plugin/app marketplace does not exist yet
Bottom line
Both are a similar lift to self-host; 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.
