Next.js Analytics for Every Render Mode

Next.js introduced a new complexity to analytics: your application renders on the server, on the edge, and in the browser - sometimes all for the same page. Traditional analytics scripts only see what happens in the browser, which means server-rendered pages, API route calls, and middleware redirects are invisible. You end up with half the picture and twice the instrumentation effort.

KISSmetrics provides a unified tracking layer across all Next.js rendering modes. Our SDK integrates with the App Router and Pages Router, automatically captures client-side navigations and server-side page renders, and provides a Node.js library for API routes and middleware. Every event feeds into the same person timeline, regardless of where it originated.

With Next.js and KISSmetrics together, you can finally answer questions like: which server-rendered landing pages drive the most signups? How do users who hit your middleware-gated features behave differently? What is the conversion path from an ISR blog post to a trial signup? The rendering mode becomes invisible - you just see people and what they do.
