About Robots.txt Checker
A robots.txt file's directives are simple individually, but reading raw text to understand which rules apply to which crawler — especially with multiple user-agent groups and overlapping allow/disallow rules — takes more careful reading than the format's simplicity suggests.
This tool parses a robots.txt file and groups its rules by user-agent, clearly showing which Allow and Disallow paths apply to each crawler group, plus any Sitemap directives listed separately — turning a flat text file into a structured view of exactly what's blocked and what's open for each bot.
This reads and displays existing robots.txt rules for understanding and auditing — for building a new one from scratch, use this site's separate robots.txt Generator tool instead, which is built for creating rules rather than parsing existing ones.
How it works
- Paste or upload a robots.txt file. Paste the content directly, or upload the file.
- Review the grouped rules. See Allow/Disallow rules organized by which user-agent they apply to.
- Check listed sitemaps. Any Sitemap directives are shown separately.
Examples
Simple robots.txt
Input
User-agent: * Disallow: /admin Allow: /
Output
A group for "*" showing Disallow: /admin and Allow: /.
