VeriFalcon
Crawl websites like a real user and find broken routes, soft 404s, JS failures, API issues, and protected-page problems before they reach customers.
JavaScript Site Crawler
For React, Vue, Next.js, and single-page applications
- Renders JavaScript
- Detects JS errors & API failures
- Supports login authentication
- ~2-5 pages/second
Static Site Crawler
For WordPress, documentation sites, blogs, and static HTML
- 50x faster than JS crawler
- Lower memory usage
- Scans up to 500 pages
- ~50-100 pages/second
Built for routes that usually get missed
Designed for release QA, technical SEO, and route-integrity monitoring.
Validate routes that only exist after JavaScript runs, including SPA navigation and partially hydrated pages.
Crawl behind login when the important failures live in customer dashboards, admin flows, or protected docs.
Use the static crawler for large documentation sets, blogs, and HTML-first sites where speed matters more than browser execution.
