Reviewer scorecard
“Open-source Knock alternative. Self-hostable and the workflow editor is well-designed. React components for in-app notifications.”
“Essential for dev teams. GitHub, CI, and alerting integrations make it the nervous system of any engineering org.”
“Open-source notification infrastructure you can self-host. The React in-app notification component saves significant development time.”
“It's bloated and expensive at scale, but there's no real alternative that matches its ecosystem. Reluctant ship.”
“Open-source notification infrastructure is the right approach. Novu's community contributions expand channel support.”
“Canvas, clips, and huddles have made it more than just chat. Great for async creative collaboration.”
