## What is Regex Blocker?

This is a Safari extension that lets you block URLs based on JavaScript Regular Expressions (Regexes). Regexes are a powerful tool that allow you to create custom and complex rules to block URLs based on certain criteria. The use of them is explained within the app, with links to further documentation. Users can edit the current blocking rules both from within the app, and within the extension pop-up in Safari itself.
The app can additionally be password protected. If password protection is set up, editing the blocking rules is no longer possible from the pop-up in Safari. Editing is then only possible from within the app, after it has been unlocked with the password.

## Key features

- Block URLs with JavaScript Regular Expressions
- Create custom and complex blocking rules
- In-app and extension pop-up rule editing

### 5/5 — Works as of iOS 18.7.1

*2026-01-30*

For people that haven’t upgraded to iOS 26, it still works! Super simple to use with regex support and password protection. It doesn’t give you the typical Safari content blocker block, the developer has made their own block screen, which does make it a bit inconsistent, meaning you may have to refresh the page to get it to appear, but it mostly works. Thanks for making this app! Update: it definitely works as of iOS 26.2.1!
