Terms of Use

Last updated: September 2026

Using the tools

The tools on this site are free to use for personal and commercial purposes. You don't need an account, and there's no usage limit.

No warranty

Every tool is provided "as is," without any guarantee that its output is error-free or fit for a particular purpose. See the Disclaimer for more detail — in short, always review generated output (like .htaccess rules or cron expressions) before relying on it in production.

Acceptable use

Please don't use these tools, especially the HTTP Header Checker, to probe systems you don't have permission to test, or for any other unlawful purpose.

Changes

These terms may be updated occasionally; continued use of the site after a change means you accept the updated terms.
