About Robots.txt Generator

The Robots.txt Generator allows you to quickly create a properly formatted robots.txt file for your website. You can define default crawling rules, configure specific search engine bots, set allow and disallow paths, add crawl delay, include sitemap URLs, and generate a ready-to-copy robots.txt file instantly.

This tool simplifies the process of generating robots.txt content without manually writing directives.

What Is a Robots.txt File?

A robots.txt file is a plain text file placed in the root directory of a website. It contains instructions for web crawlers (search engine bots) about which parts of the website they are allowed or not allowed to access.

A robots.txt file may include directives such as:

  • User-agent

  • Disallow

  • Allow

  • Crawl-delay

  • Sitemap

  • Host

This generator creates properly structured directives based on your selections.

This tool supports the following features:

  • Set default crawling behavior for all robots

  • Configure specific user-agents individually

  • Add multiple allow paths

  • Add multiple disallow paths

  • Set crawl-delay for bots

  • Add a sitemap URL

  • Add a host directive

  • Add custom user-agents

  • Bulk allow or disallow all listed bots

  • Copy generated robots.txt to clipboard

How the Robots.txt Generator Works

The process is simple:

Step 1: Set Default Robot Behavior

Choose how all unspecified robots should behave:

  • Default

  • Allowed (full access)

  • Disallowed (block all access)

Step 2: Configure Crawl Delay (Optional)

Select a delay value in seconds to control how frequently bots crawl your site.

Step 3: Add Sitemap URL (Optional)

Provide the full URL to your sitemap.xml file.

Step 4: Set Host (Optional)

Enter your preferred domain name for the Host directive.

Step 5: Configure Paths

Add:

  • Allow paths (one per line)

  • Disallow paths (one per line)

The tool automatically counts how many paths you have added.

Step 6: Configure Specific User-Agents

You can:

  • Allow specific bots

  • Disallow specific bots

  • Leave them as default

  • Apply bulk actions to all bots

  • Add a custom user-agent manually

Step 7: Generate Robots.txt

Click “Generate Robots.txt” and the tool creates structured output based on your configuration.

Default Rules for All Robots

You can control the behavior of all robots using the Default Robot Behavior option:

Allowed

Generates:

User-agent: * Disallow:

Disallowed

Generates:

User-agent: * Disallow: /

Default

No default rule block is generated unless other configurations are added.

Path Configuration

Allow Paths

Enter one path per line to explicitly allow access.

Example:

/public /images /css

Each valid line generates:

Allow: /path

Disallow Paths

Enter one path per line to block specific directories.

Example:

/admin /private

Each valid line generates:

Disallow: /path

The tool automatically trims empty lines and ignores blank entries.

User-Agent Configuration

The generator includes a preloaded list of common search engine crawlers.

Each user-agent has three status options:

  • Default

  • Allowed

  • Disallowed

Only user-agents set to Allowed or Disallowed are included in the generated file.

Bulk Actions

You can:

  • Allow All user-agents

  • Disallow All user-agents

  • Reset all to Default

The interface updates instantly with visual indicators.

Add Custom User-Agent

You can manually add any crawler name.
The tool prevents duplicate user-agent names (case-insensitive).

Custom agents behave exactly like built-in agents.

Crawl-Delay Directive

If selected, the tool adds:

Crawl-delay: X

Crawl delay is applied:

  • To the default block (if generated)

  • To each configured user-agent (unless disallowed)

Sitemap Directive

If provided, the tool appends:

Sitemap: https://example.com/sitemap.xml

The sitemap directive is placed at the end of the file.

Host: example.com

The Host directive is placed at the top of the file.

Frequently Asked Questions About Robots.txt Generator

Learn how to generate, customize, and optimize your robots.txt file with our free online generator tool.

If no rules are generated (no default behavior, no user-agents, no paths, no sitemap, no host), the backend automatically returns a basic allow-all robots.txt with a comment indicating it was generated by the tool.

No.
Only user-agents explicitly set to Allowed or Disallowed are included in the generated robots.txt. User-agents left as Default are ignored.

Empty or whitespace-only lines are automatically ignored.
Only valid, non-empty paths are converted into Allow: or Disallow: directives.

Yes.
The tool uses the same Allow and Disallow path inputs for all configured user-agents. Paths are applied consistently to each user-agent block generated.

The tool prevents duplicate custom user-agents.
If a user-agent name already exists (case-insensitive), it will not be added again and a notification is shown.

 

If provided, the Host: directive is always placed at the very top of the robots.txt file before any User-agent rules.

 

Yes, our Robots.txt Generator Tool is 100% free and requires no sign-up or installation. You can generate and download unlimited robots.txt files anytime.
