robots.txt Generator

Build a robots.txt with multiple user‑agent blocks, Allow/Disallow, optional Crawl-delay, Host, and Sitemap lines. Live preview updates as you type.

User‑agent blocks

Global

Sitemap URLs (one per line) Host (optional; used by some crawlers)

Notes: Host is honored by some crawlers (e.g., Yandex). Crawl-delay isn’t used by Google but may be used by others. Wildcards * and $ are widely supported (not in the core RFC).

Preview (robots.txt)

URL tester

User‑agent URL or path

Reminder: robots.txt is publicly accessible and is an advisory for well‑behaved crawlers; it’s not an access control mechanism.
