What is Robots.txt Generator?
Generate a clean robots.txt file with user-agent, allow, disallow, and sitemap directives.
- Generate robots.txt directives
- Add sitemap location
- Create allow and disallow rules
How to use it
- Paste the robots.txt content you want to process.
- Adjust quality, size, or output options when available.
- Run the tool to generate robots.txt and preview the result on the page.
- Copy the output or download the generated file when it looks right.
Best use cases
- Clean developer data during debugging, API work, and documentation.
- Clean content before saving configs, sharing snippets, or importing tables.
- Use it when privacy matters and the input should stay inside the browser.
Official standards and scope
RFC 9309 standardizes the Robots Exclusion Protocol and Google documents deployment rules for robots.txt. This page reads one key=value pair per physical line, with later duplicate keys replacing earlier ones, then emits exactly one User-agent group followed by Allow and Disallow records and one Sitemap line. Multiple paths can only be supplied as comma-separated values on the same key line; continuation lines without an equals sign are ignored. The generator does not validate product tokens, path patterns, percent encoding, record length, file size, UTF-8, sitemap URL, host scope, duplicate rules, group precedence, or crawler-specific extensions, and it cannot build multiple agent groups. Defaults are DataHub-oriented. robots.txt is a crawl hint, not authentication or a reliable noindex mechanism. Review the public root URL, crawler behavior, and any sensitive paths before deployment.

Notes
- Browser support for robots.txt can affect preview and export behavior.
- Invalid input will show an error when possible, but the tool will not guess missing fields.
- Preview the result before using it in production, publishing, or submission workflows.
FAQ
Will it block every crawler?
robots.txt is a crawler instruction, not access control. Sensitive pages need server-side protection.
Is Robots.txt Generator free to use?
Yes. You can use it directly in the browser without creating an account.
Does Robots.txt Generator support batch processing?
Text tools usually process one pasted input at a time, so split large jobs into smaller inputs.
Are files or content uploaded?
Robots.txt Generator runs in your browser, so your input or files are not uploaded to DataHub servers.
Can I use Robots.txt Generator on mobile?
Yes, but desktop browsers are better for large files, batch conversion, or long text input.
Why can conversion or validation fail?
Common causes include invalid syntax, missing required fields, or invisible characters copied with the input.
Can I use the result commercially?
The tool only processes your own input. Commercial use depends on the rights of the original file or data.
