Open Source Dittofeed Alternatives

Novu gives developers a single platform to handle notifications across every channel: in-app inbox, email, push, SMS, and chat. Instead of wiring together separate providers for each channel, you get one API and a visual workflow editor that covers the full delivery pipeline.

The embeddable <Inbox /> component drops a fully functional notification center into any React, Next.js, or Remix app. It includes real-time delivery, user preference controls, snooze, read/archive states, and tabbed filtering out of the box. The visual appearance is customizable to match your product.

For email, Novu includes a block-based editor powered by React Email. Build and preview templates without touching raw HTML. A digest engine batches multiple events into a single message, which cuts noise on things like comment threads or activity feeds.

Workflows can start in the UI and graduate to code when you need runtime logic, local data access, or tighter control over branching. If you've looked at alternatives like Knock or Courier, Novu covers similar ground but with a self-hostable option. Integrations include Twilio, Resend, Clerk, and Stripe.

The free tier includes 10,000 events per month. The project has over 36,000 GitHub stars and 400+ contributors.
