Frequently asked questions
What's the main difference between Knock and Novu?
Knock provides a developer-first notification infrastructure with React components, real-time feeds, and native cross-channel orchestration. It delivers enterprise-grade features like advanced batching, complex workflows, and production-ready components that integrate seamlessly with your existing stack.
As an open-source solution, Novu has prioritized out-of-the-box features while sacrificing the flexibility and deep customization that Knock provides.
For example, Novu provides a default interface to manage workflow channel preferences at the subscriber level. Knock's preference model supports this, but also provides a way to model tenant-specific preferences for multi-tenant applications and more advanced preference conditions to power something like usage-based billing, e.g. 'I only want to get an email when my usage exceeds 70%.'
Another example is how Knock architects its client-side SDKs. Novu has prioritized a component-based experience using its <Inbox> component and then only exposes a singular `Novu` JavaScript client. This means it's easy to get started, but more difficult to customize if you need specific design or functionality, which we find is often the case with many enterprises. Knock, on the other hand, exposes React components, React hooks, and a JavaScript client for all of our in-app features. This means that it's equally easy to get started, but you never have to sacrifice your product requirements because we provide lower-level abstractions.
In almost every case, you'll find that Knock is better suited for technical teams because of this approach to providing more flexible abstractions.
Which platform scales better for high-volume notifications?
Knock is built for enterprise scale, processing billions of notifications monthly with guaranteed delivery and idempotency. Our infrastructure provides horizontal scaling, message queuing, and delivery guarantees that platform teams require. We serve companies from startups to enterprises with thousands of employees.
Which platform provides better developer experience and documentation?
Knock is consistently praised for a superior developer experience, with comprehensive documentation, TypeScript support, and modern SDKs. Our React components and clean APIs enable developers to build faster while maintaining code quality. Developers particularly value our debugging tools and clear error handling.
What's the difference in pricing and cost predictability?
Both Knock and Novu offer transparent, usage-based pricing that scales with your business. Knock’s pricing tiers make it accessible for startups and growing companies, with volume discounts for larger enterprise organizations. All plans include unlimited data ingestion and unlimited channels with no onboarding or service fees, and overages are only incurred by volume of sent messages. See more pricing information here.
Which platform is easier to implement?
Knock is designed for rapid implementation by developers, with most teams shipping notifications within hours by using our React components and SDKs. Knock customers report implementing complete notification systems in days rather than months. Using the Knock Management API, CLI, and MCP server, product teams can automate their work using AI tools like Cursor or Claude Code to create notification features. Currently, Novu does not have the same capability and lacks an API to manage workflows, template, or layouts.
How long does migration from Novu to Knock take?
Most engineering teams migrate from Novu to Knock within 2-4 weeks, depending on notification complexity. Knock's responsive support team help accelerate the process. The investment pays off quickly through improved developer productivity and reduced maintenance.
