Robots.txt Generator for Crawler Rules

Draft robots.txt rules for public websites, staging sites, blocked paths, sitemap directives, preferred hosts, and common AI crawler controls without sending anything to a server.

Loading...
Quick answer

Robots.txt gives crawlers instructions about which paths they should or should not crawl.

It should live at the root of your domain.

Best inputs

Public path list

Block only paths that should not be crawled, such as admin, API, dashboard, or private folders.

Real sitemap URL

Use the production sitemap URL that crawlers should discover from robots.txt.

How robots.txt works
Rules are grouped by crawler user agent, then interpreted as crawl directives.

User-agent: * Disallow: /admin

Most robots.txt files use User-agent, Allow, Disallow, and Sitemap lines. Specific crawler policies can be added in separate blocks.

Crawler control is not access control

Robots.txt is a public instruction file. It should not be used to protect secrets, private documents, admin data, or sensitive URLs.

Use authentication and authorization for private content, and use noindex or removal tools for index cleanup workflows.

Common use cases
These are the jobs people usually mean when they search for a robots.txt generator.

Public site launch

Allow crawling, block admin or API paths, and include the sitemap URL.

Staging environment

Create a temporary block-all draft for test domains that should not be crawled.

AI crawler policy

Add common crawler-specific blocks for review before publishing.

SEO QA

Draft rules before checking them with a crawler or search console tool.

Example, assumptions, and limitations
Review crawler rules carefully before deploying them to production.

Example

A public site can allow root crawling, disallow /admin and /api, and include a sitemap directive.

Assumption

The generated file will be reviewed and placed at the domain root as /robots.txt.

Limitation

Robots.txt is advisory for compliant crawlers and does not secure private content.

Frequently asked questions

Can robots.txt block Google from indexing a page?

It can block crawling, but it is not a guaranteed noindex mechanism. Use noindex for index control.

Should I include a sitemap line?

Usually yes. A Sitemap directive helps crawlers discover your XML sitemap location.

Can I block all crawlers on staging?

Yes, but also use authentication. Robots.txt alone is not security.

Does this validate live robots.txt?

No. It generates a local draft. Use a crawler or search console tool to validate deployed files.

Suggested workflow

Crawl control QA path

Draft crawler rules, check sitemap coverage, and add page-level index controls when needed.
