nginx

The nginx collector is a dynamic module. Install it on the host that terminates TLS, so the record carries the request as the client sent it.

Run one command as root:

curl -fsSL https://get.nemel.app/nginx.sh | sh -s -- --site example.com

It drops ngx_nemel_module.so into your modules directory, adds the load_module line and one nemel_site directive to your server block, and reloads nginx. Records appear on your dashboard within a minute; if none do, run the same command with --check.

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