SynthTrail

Agent analytics for sites behind Cloudflare and other CDNs

If your site sits behind a CDN, SynthTrail still works. It is a plain script tag in your pages, so it runs in the visitor's browser whatever sits in front of your server.

The problem: the edge sees requests, not behaviour

CDNs and edge workers are excellent at counting and filtering requests. They cannot see clicks, typing or scrolling inside a page, so they cannot show what a browser-driven agent did once it got through.

How SynthTrail fits

You add one script tag to your pages. Nothing is installed at the edge, and there is no worker or proxy rule to maintain. The snippet loads asynchronously and reports flagged sessions only.

What it is not

There is no dedicated edge-worker integration, and it does not read your CDN logs. If you use a script manager, add the snippet as a normal script. Keep edge tools for blocking and rate limits, and use SynthTrail for the trail.

What you get

Works behind any CDN or proxy
No edge code to deploy
In-page trails your edge tools cannot see
Reports only, so nothing is blocked by mistake

Follow the trail on your own site

Paste one snippet and see the synthetic visitors that use your site. Card details are entered on Stripe, never on this site.
