## What it is
wBlock is an open-source, next-generation ad blocker built as Safari content-blocking extensions for macOS, iOS, iPadOS, and visionOS. It supports 750,000 filter rules across five extensions, Protocol Buffer storage with LZ4 compression, iCloud sync, element zapping, and autoplay blocking.

## Use cases
- block ads in Safari on iPhone and Mac
- hide annoying page elements with an element zapper
- stop videos from autoplaying in Safari
- sync filter lists and whitelist across Apple devices
- use large filter lists like uBlock Origin in Safari
- block trackers and ads without slowing down browsing

## When to choose
- you use Safari on macOS, iOS, iPadOS, or visionOS and want a powerful open-source ad blocker
- you need more filter rules than Safari's default single-extension limit allows
- you want iCloud sync of filters and settings across Apple devices
- you want element-level hiding and autoplay prevention

## When to avoid
- you use Chrome, Firefox, or another non-Safari browser
- you need a cross-platform ad blocker outside the Apple ecosystem
- you prefer a fully managed closed-source solution with commercial support
