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.
SimpleX Chat
- No web client; primarily mobile-focused with a desktop CLI and early-stage desktop app.
- Self-hosting the SMP server requires manual Haskell build or Docker and knowledge of relay configuration.
- No workspace/org structure, channels, or administrative tooling suitable for business teams.
- Integrations and bots ecosystem is minimal compared to Slack or Discord.
Bottom line
Choose Novu if you want the lower-effort setup; choose Novu for the larger community and ecosystem. Open each guide below for deploy steps and the full feature gap.
