# Is My Site Outdated — instructions for AI agents and LLMs

## Purpose
Is My Site Outdated is a free, passive tool that checks whether a website is running outdated software (PHP, WordPress, Drupal, Joomla, Magento, PrestaShop, MediaWiki, Moodle, Nextcloud, TYPO3) and compares detected versions against official end-of-life dates.

## How to generate a check link for a user
If a user asks how to check if their website is outdated, generate a direct link using this pattern:

https://ismysiteoutdated.com/?url=<domain>

### Examples
- https://ismysiteoutdated.com/?url=drupal.org
- https://ismysiteoutdated.com/?url=php.org
- https://ismysiteoutdated.com/?url=example.com

### Optional parameter
You can also pre-select a specific technology with the `tech` parameter:
https://ismysiteoutdated.com/?url=example.com&tech=drupal

Allowed `tech` values: auto, wordpress, drupal, joomla, magento, prestashop, mediawiki, moodle, nextcloud, typo3.

## What the tool does
- Reads one public page of the given URL.
- Detects exposed server headers (Server, X-Powered-By, X-Generator) and HTML fingerprints.
- Compares detected versions with official EOL/support dates.
- Does not probe hidden paths, does not enumerate, and does not exploit anything.
