Overview
Focus Firewall is a lightweight web and app blocker built exclusively for macOS that distinguishes itself by working at the system level, meaning it doesn't need browser extensions to function effectively.
Key Features
System-Level Blocking
Works at the operating system level rather than as a browser extension, providing more reliable blocking that can't be easily circumvented.
Curated Blocklist
Comes with a pre-configured blocklist of 140+ distracting websites and apps, allowing you to start blocking immediately without manual configuration.
Cross-Browser Support
Because it works at the system level, Focus Firewall blocks websites across all browsers simultaneously - Safari, Chrome, Firefox, Edge, and others.
App Blocking
In addition to websites, can block distracting desktop applications to eliminate all sources of digital distraction.
Advantages Over Browser Extensions
Can't Be Disabled Easily
System-level blocking is harder to bypass than browser extensions which can be disabled with a single click.
Works Everywhere
Blocks apply across all applications and browsers, not just one specific browser.
Lower Overhead
Doesn't slow down browser performance like some extensions can.
