Robots.txt Generator.

Robots.txt Generator is a high-performance web utility built to generate a valid robots.txt file to control which pages search engines and AI bots can crawl. Set crawl delay, block AI agents, and add your sitemap URL instantly and securely. Because it is designed with a local-first architecture, all processing occurs directly in your browser's memory using client-side JavaScript. This ensures that your files, code, or private text inputs are never uploaded to any external server or tracked by third-party analytics.

Whether you are formatting source code, cleaning text files, converting file structures, or running diagnostics, running these processes locally in your browser memory sandbox eliminates network latency and protects your data privacy.

Frequently Asked Questions (FAQs)

Where do I upload my robots.txt file?

Upload robots.txt to your website's root directory so it is accessible at https://yourdomain.com/robots.txt. Every crawler checks this exact URL before crawling any other page.

Does robots.txt prevent pages from being indexed?

Blocking a URL in robots.txt prevents crawlers from visiting it, but does not automatically remove it from search index if it was already indexed or if other pages link to it. To fully prevent indexing, use a noindex meta tag on the page itself in addition to blocking in robots.txt.

Should I block AI crawlers like GPTBot?

This is a personal business decision. Blocking AI bots prevents your content from being used to train large language models, but has no effect on traditional search engine rankings. Major AI bots (GPTBot, ClaudeBot, Google-Extended) respect robots.txt directives. If your content is commercially valuable and you do not want it used for AI training, blocking these bots is reasonable.

What does Crawl-delay do?

Crawl-delay tells crawlers to wait a specified number of seconds between requests. This reduces server load if your hosting cannot handle rapid consecutive requests from bots. Note: Google does not honor Crawl-delay in robots.txt — use Google Search Console's crawl rate settings instead for Googlebot.
