Enter a public URL and select up to eight crawlers or browsers, including a custom User-Agent.
Compare the HTML returned to search bots and everyday browsers. Check redirects, review full source, and preview up to eight User-Agent responses side by side.
We fetch the public HTML once for each selected User-Agent.
A changed response can result from User-Agent targeting, legitimate mobile variations, redirects, cookies, geo/IP filtering, or anti-bot rules. These requests imitate User-Agent headers; they are not real verified Googlebot/Bingbot crawls. Preview is static: scripts are disabled.
Enter a public URL and select up to eight crawlers or browsers, including a custom User-Agent.
PHP requests the public page separately per profile, following and checking each redirect.
Switch every card together between static visual previews and the full HTML returned by the server.
No. Mobile layouts, personalization, access restrictions, and redirects may legitimately return different HTML. Inspect the differences in context.
No. Bovolab sends a Googlebot User-Agent header from its own server. A website can also identify a real bot by IP, reverse DNS, cookies, or JavaScript behavior.
No. For safety, the visual preview renders static HTML with scripts disabled. You may optionally load remote CSS and images for closer visual fidelity.
No. Crawled HTML is processed in server memory and returned to your browser. Bovolab does not create a history database or save the response files. Standard infrastructure logs may still exist.
