Support and how it all works

Create your account and pay on Stripe's checkout page. Your account page then shows your personal snippet. Copy it and paste it just before the closing body tag on every page of your website, then publish your site.

Open your published site with ?synthtrail_test=1 on the end of the address, for example yoursite.com/?synthtrail_test=1. Click through a few pages and submit a form. After about ten seconds, open Sessions in your dashboard and press Refresh. Your visit appears as a trail.

The snippet checks whether the browser names itself as a known AI agent, reports automation or runs headless, fires scripted clicks and typing, or opens pages faster than a person could. Each flagged session lists the reasons it was flagged.

SynthTrail runs inside the page. A crawler that only downloads HTML never runs the snippet, so it can't be seen this way. Your server logs are the right place for that traffic.

Exposed keys and tokens in page source, downloadable environment, backup and source-history files, open admin and data routes, readable login cookies, hidden fields holding secrets and insecure http content. Each finding lists a plain-language fix.

Only sessions flagged as synthetic are saved, as an event trail of pages, clicks, scrolls and form submits. There is no video, and typed values are not recorded. Ordinary human visits are not stored.

Open your account page and choose Manage billing and invoices. It opens Stripe's billing page, where you can update your card, download invoices and cancel.
