SynthTrail

Single-page app AI crawler rendering and DOM audits

Single-page apps build their content in the browser. SynthTrail runs in the finished page, so it scans what your app actually renders and tracks the agents that load it.

The problem: two versions of your page

A single-page app sends a thin shell, then builds the real page with JavaScript. What a plain crawler fetches and what a browser agent sees can differ, and secrets can slip into either one.

What the audit reads

The scan reads the rendered page, not the empty shell, looking for keys and tokens, sensitive comments, hidden fields, readable cookies and browser-stored tokens, and mixed insecure content.

Tracking in an SPA

Sessions record the page load, clicks, scrolls, field changes and form submits. Route changes inside the app that do not reload the page are not separately recorded as new pages today, so a session may show fewer pages than a person navigated.
