Knock is infrastructure for sending product and customer messaging. Ship cross-channel product notifications and lifecycle messaging that drives engagement, growth, and retention.
Built by developers, for developers. You get full observability and analytics about your message and user behavior, environments, git-like version control, and top-notch SDKs.
Start sending cross-channel messaging in minutes.
If you don’t have a Knock account, you’ll be prompted to create one during the Vercel integration setup flow.
When you connect a Vercel project to an account in Knock, Knock will automatically set the KNOCK_API_KEY and KNOCK_PUBLIC_API_KEY environment variables on your Vercel project.
To learn how to use Knock to send notifications to your users, read our quick start guide.
