About this tool

What robots.txt Generator does

A robots.txt Generator that creates plain text files to control how search engine crawlers access and index a website. Users specify which bots to allow or block, add disallowed or allowed paths, include sitemap URLs, and set crawl delays. The output is standard code that can be copied to the clipboard or downloaded as a file to place at the root of a domain. The DevBolt version runs entirely in the browser, so no data leaves the user's device. It offers presets like "Allow All," "Block All," and "Block AI Bots," plus a standard website template. Users can select from a list of common bots—including Googlebot, Bingbot, and AI crawlers—or add custom user‑agents. The interface includes fields for crawl delay and sitemap input, and the generated file preview shows the exact syntax before copying or downloading.

Do I need to upload the generated robots.txt file somewhere for it to work?
Yes, the file must be placed at the root of your domain (e.g., https://example.com/robots.txt) for search engines to find and read it.
Can I block specific AI crawlers like GPTBot or ClaudeBot?
Yes, the tool includes presets and a dropdown list that lets you select or deselect AI bots such as GPTBot, ClaudeBot, CCBot, and others.
Is the robots.txt file generated by this tool valid for all search engines?
The syntax follows the standard robots.txt protocol, so it is compatible with Google, Bing, Yahoo, and other major crawlers that support the format.
What happens if I choose the "Block All" preset?
The generator creates a robots.txt that disallows all crawlers from accessing any part of the site, effectively hiding it from search engine indexes.
