    Frequently asked questions

    Does this tool use any external parsing library?

    No. All parsing logic runs inline in your browser with custom regex patterns. No external libraries or API calls are used.

    Can it detect bots and crawlers?

    Yes. The parser recognizes major search engine bots like Googlebot and Bingbot, social media crawlers, AI bots like GPTBot and ClaudeBot, and common SEO tool crawlers.

    Why does my browser show as Chrome when I use Brave or Edge?

    Brave and Edge are Chromium-based and include Chrome in their user-agent string. The parser checks for Brave and Edge identifiers first, but Brave in particular often hides its identity for privacy reasons.

    Is my user-agent string sent to any server?

    No. All parsing happens entirely in your browser. Nothing is uploaded or transmitted.

    What rendering engines does the parser identify?

    It detects Blink (Chrome, Edge, Opera), Gecko (Firefox), WebKit (Safari), Trident (Internet Explorer), Presto (old Opera), and EdgeHTML (legacy Edge).
