Cloudflare

The Cloudflare collector is a passthrough Worker bound to the route in front of your origin. It reads the request, answers with your origin's response untouched, and forwards the record out of band.

Run one command in the directory of the project you deploy from:

npx nemel@latest install cloudflare --site example.com --zone example.com

It creates the Worker, binds it to example.com/* and writes your site key into the deployment. The Worker adds no latency your origin does not already spend.

Other platforms: nginx, Vercel. Tiers and limits are on the pricing page.
