How to use

Enter robots.txt and Path into robots.txt Tester and press Run. DevUtility calculates in your browser with a pure JavaScript engine (Web Worker for heavy inputs). The selected inputs are not sent to a Tolari processing endpoint; output behavior depends on the operation.

Steps

  1. Use the embedded robots.txt Tester on this page (or open the full tool).
  2. Enter robots.txt and Path.
  3. Press Run (Ctrl+Enter).
  4. Copy or download the result, or share a link to this tool.

FAQ

Is robots.txt Tester really free?

Yes. No account or credits are required, and no paywall blocks the task. Browser, device, and stated file-size limits still apply. Ads may appear only when configured and enabled after the required consent signal.

Is anything I type into robots.txt Tester sent to a server?

The calculation runs in this page and is not sent to a Tolari processing server. Depending on your settings, recent runs may be saved in local browser storage; use Private Mode or clear local history on this device if needed.

What should I enter in "robots.txt"?

Put your robots.txt here — for example: User-agent: * Disallow: /admin. Leave the defaults first to see how it works, then adjust. Every field is validated with a plain-language message if something is off.

How should I compare robots.txt Tester with other options?

Compare supported inputs, output quality, file-size limits, browser compatibility, and privacy terms using the same sample. Provider features and terms can change; check their current documentation.

How accurate is robots.txt Tester?

This tool computes in your browser when run. Results depend on the selected inputs, browser support, and the specific operation.
