Novu
Open-source notification infrastructure for multi-channel developer alerts
Overview
Novu is a full-stack notification infrastructure platform that gives developers a unified API to send notifications across email, SMS, push, chat, and in-app channels. It provides a visual workflow editor to design multi-step notification sequences, subscriber management, and provider integrations for services like Sendgrid, Twilio, FCM, and Slack. It deploys via Docker Compose and exposes a REST API plus SDKs for major languages.
Where it falls short of Slack
- 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.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
