What is a Pi-hole Regex Generator?
A Pi-hole Regex Generator is a tool that helps you create custom regular expressions (Regex) for blocking ads, trackers, or other unwanted domains in Pi-hole. Unlike simple domain blocking, Regex allows you to match multiple domains with a single rule.

How does it work?
The generator creates Regex patterns that tell Pi-hole which domains to block while excluding specific subdomains you want to keep accessible. For example, you could block all ad-serving domains on a website but allow essential subdomains like cdn.example.com or shop.example.com.

What is it used for?
This tool is used to:

• Fine-tune Pi-hole ad and tracker blocking
• Avoid accidentally blocking useful subdomains
• Save time by generating accurate Regex patterns automatically
• Make Pi-hole more precise and user-friendly

Using a Pi-hole Regex Generator makes blocking unwanted content more flexible and safe, ensuring you don’t accidentally break websites you want to use.
