Alphorn vs Novu
Simpler architecture, same self-hosting freedom
Novu is a powerful notification infrastructure platform, but its complexity can be overkill for teams that just need reliable webhook-to-channel routing. Alphorn is focused, lightweight, and runs on PostgreSQL alone.
Why teams choose Alphorn
PostgreSQL only — no Redis, no MongoDB
Novu requires MongoDB and Redis alongside its services. Alphorn runs on a single PostgreSQL database, dramatically simplifying self-hosted deployments.
One container, not a microservice fleet
Alphorn ships as a single deployable unit (web + worker). No service mesh, no message broker, no container orchestration required.
Transparent, predictable pricing
Alphorn's pricing is based on messages with clear limits. No workflow-run abstraction, no surprise overages from fan-out.

Frequently asked questions
When should I choose Novu over Alphorn?
Novu is a better fit if you need in-app notification inboxes, complex multi-step workflows with branching logic, or digest/batching at the workflow level. Alphorn is better for straightforward webhook-to-channel routing with minimal infrastructure.
Can I migrate from Novu to Alphorn?
Yes. If you're using Novu primarily for channel delivery, you can point your triggers at Alphorn's webhook endpoint instead. Alphorn accepts standard JSON payloads — no SDK swap needed.
Is Alphorn as feature-rich as Novu?
Alphorn focuses on doing one thing well: routing notifications to channels with filtering and retries. Novu offers more features (in-app inbox, digest, preferences), but with more infrastructure complexity.
