Case Study: Vercel powers scalable notifications with Knock

Vercel - Customer Case Study

Vercel, the frontend developer platform, needed a fast and flexible way to build notification systems at scale. The team was evaluating options and wanted to quickly launch an in-app notification feed, support multi-channel messaging, and give users control over notification preferences without adding heavy engineering overhead, so they chose Knock and its workflows, React library, and in-app/email channels.

With Knock, Vercel got an in-app feed demo running in less than an hour and used the dashboard, workflow editor, and live previews to build notification layouts and real-time feeds. Knock also helped them debug notifications with analytics, update preferences without redeploying infrastructure, and let customer success and product teams make changes independently, improving iteration speed and reducing engineering dependence.
