Vercel

The Vercel collector is middleware in your own project. It runs before every matched route and reports the request the platform actually received, including the ones your application returns from its cache.

Run one command in your project:

npx nemel@latest install vercel --site example.com

It adds middleware.ts (or extends the one you have) and sets the site key as a project environment variable. The Vercel collector is part of the Pro tier and above; see pricing.

Other platforms: nginx, Cloudflare.
