Fortely crawls your site on a schedule and diffs every scan against your baseline — flagging title, meta, canonical, robots.txt, sitemap, and structured-data changes the moment they ship.
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.
Whether you ship with Next.js, Astro, SvelteKit, or a legacy stack, Fortely crawls your live site with a real headless browser — not just your source code — so it catches what actually ships to Google: title and meta description drift, canonical mistakes, sitemap shrinkage, and structured-data errors, diffed against your last baseline so you only see what changed.
