Robots.txt Generator
Form-based robots.txt builder with download.
Robots.txt Generator builds a clean robots.txt from form options—user-agent rules, Allow/Disallow paths, optional crawl-delay, host, and sitemap—locally in your browser with copy and download.
How it works
Enter a user-agent, list allow and disallow paths (one per line), and optionally add sitemap, crawl-delay, and host directives. The output updates live so you can copy or download robots.txt.
Benefits
- Form-driven robots.txt without memorizing directive order
- Copy and download the finished file
- Optional sitemap and crawl-delay fields
- Runs fully client-side
Use cases
- Draft production robots.txt for a marketing site
- Block staging environments from polite crawlers
- Add a Sitemap line pointing at your XML index
- Experiment with path rules before deploying
Best practices
- Keep robots.txt at the site root over HTTPS
- Do not rely on Disallow for secrecy
- Point Sitemap to a valid absolute URL
- Test with your search engine’s robots testing tools after deploy
Common mistakes
- Blocking CSS/JS needed for rendering
- Using robots.txt instead of noindex for thin pages you still crawl
- Assuming every bot honors Crawl-delay
- Leaving staging open with User-agent: * and empty Disallow
Privacy
Robots.txt Generator runs locally. ToolHub does not receive your paths or sitemap URL unless you enable on-device history.
Frequently asked questions
- What does the Robots.txt Generator create?
- It builds a robots.txt from user-agent, Allow/Disallow paths, optional Crawl-delay, Host, and Sitemap lines—ready to copy or download.
- Does robots.txt guarantee pages stay private?
- No. robots.txt is a crawler courtesy file. Sensitive content needs authentication. Disallow does not encrypt or hide URLs from users.
- Is Crawl-delay widely supported?
- Crawl-delay is non-standard. Some crawlers honor it; Google generally ignores it. Prefer crawl controls in Search Console when available.
- Can I block indexing with robots.txt alone?
- Disallow can reduce crawling, but use noindex meta/headers when you need stronger indexation control for URLs that may still be discovered.
- Does this tool upload my rules?
- No. Generation runs entirely in your browser. Download the file and deploy it to your site root yourself.
