Traditional web generators upload your disallow paths and internal admin routes to remote servers. HiMat's Robots.txt Generator runs 100% locally in your web browser. Zero server logs, zero analytics harvest, and complete privacy.
A robots.txt file (Robots Exclusion Protocol, RFC 9309) gives instructions to web robots and search crawlers about which URLs on your site they can or cannot access, conserving crawl budget and protecting private endpoints.
No. The HiMat Robots.txt Generator operates 100% locally in your web browser. Neither your disallow paths, site domain, nor XML sitemap locations are transmitted across the network.
Our tool includes dedicated toggles and presets for AI scrapers. Selecting AI Bot Opt-Out adds standard `User-agent: GPTBot` and `User-agent: ClaudeBot` disallow rules while leaving Googlebot and Bingbot enabled.
The interactive URL tester parses your generated directives locally in browser memory using wildcards (`*`) and path prefix matches according to RFC 9309 rules, instantly displaying whether a path is ALLOWED or DISALLOWED for a given User-Agent.
