JavaScript site crawler for real browser behavior
Use VeriFalcon when the important failures happen after the browser arrives: client-side navigation, hydration, API-backed routes, auth redirects, or JavaScript-rendered links that static crawlers never really verify.
The current product includes a live crawl feed with stats, heartbeat updates, and issue panels so teams can see whether the scan is still making progress.

Concrete Evidence Behind This Page
The current product includes a live crawl feed with stats, heartbeat updates, and issue panels so teams can see whether the scan is still making progress.
The JavaScript path does not stop at status codes. It tracks JS errors, API failures, protected routes, blocked routes, timeouts, and scanner errors as separate outcomes.
The crawler runs through a BrowserManager with page, context, and browser recycling limits because long-running Playwright scans need operational safeguards, not just a browser launch.
Screens From The Current JavaScript Workflow
Why JavaScript crawling matters
Modern product sites, docs portals, and app shells increasingly hide the meaningful route behavior behind hydration, client routing, and fetch-heavy rendering. A plain HTTP crawler can tell you the initial document responded. It cannot reliably tell you whether the route stayed healthy once the browser executed the page.
That is the gap VeriFalcon is built for. It follows the route as a user sees it and keeps the output grouped by the failure classes teams actually fix.
Best-fit use casesBest fit includes SPA navigation, partial hydration, and authenticated route surfaces.
- React and Next.js marketing sites
- single-page apps with internal routing
- customer dashboards behind login
- documentation sites with client-side search or navigation
What you get back from the current product
The current results surface separates broken pages, broken resources, protected routes, JS errors, API failures, scanner issues, and pages discovered but not crawled. It also supports live scan updates, grouped-link views, and exports, which makes the output more useful than a generic pass/fail crawl log.
That is why this page is framed as a JavaScript site crawler page, not as a vague promise about 'AI website monitoring' or a catch-all SEO suite.
FAQ
When should I use the JavaScript crawler instead of the static crawler?
Use the JavaScript crawler if route rendering, navigation, or page content depends on JavaScript, hydration, or authenticated state.
Can I still crawl a simple docs site?
Yes, but for pure static content the static crawler will usually be faster and cheaper.
