The open-source communication infrastructure for agents and products
What novu is
Every product and every agent eventually needs to talk to people, across the channels those people already use. Novu is the open-source layer that handles that communication for you, so you don't rebuild Inbox feeds, provider integrations, and channel webhooks from scratch every time.

Knock charges $99 a month for notification infrastructure. Novu does it free. It's an open-source platform that routes all your alerts through one API — email, SMS, push, in-app, even chat — so your team manages every channel from a single workflow builder instead of wiring up five separate providers. Over 35,000 developers have starred it, and companies use it to send millions of notifications without juggling SendGrid, Twilio, and Firebase dashboards. Star it if this saved you money.
