Every crawl loads your pages in a real headless browser and records uncaught exceptions and console errors, diffed against your last scan so you see new errors, not the ones you already know about.
Paste a URL — Fortely fingerprints your framework, host, sitemap, and robots.txt in seconds.
Choose how often to scan, from every 4 hours to weekly, and a mobile / desktop / both device profile.
Every scan is diffed against your last baseline — you only hear about what actually changed.
Fortely isn't a replacement for a runtime error tracker like Sentry — it doesn't see every real visitor's session. What it does is load every selected page in a real headless browser on your schedule and record what breaks, so a bad deploy that throws console errors on your homepage or checkout page gets flagged on the next scan, not whenever a user happens to report it.
