Zen is an open-source system-wide ad-blocker and privacy guard for Windows, macOS, and Linux. It works by setting up a proxy that intercepts HTTP requests from all applications, and blocks those serving ads, tracking scripts that monitor your behavior, malware, and other unwanted content. By operating at the system level, Zen can protect against threats that browser extensions cannot, such as trackers embedded in desktop applications and operating system components. Zen comes with many pre-installed filters, but also allows you to easily add hosts files and EasyList-style filters, enabling you to tailor your protection to your specific needs.

Zen 是一款适用于 Windows、macOS 和 Linux 的开源系统级广告拦截器和隐私保护工具。它的工作原理是设置一个代理，拦截所有应用程序的 HTTP 请求，并阻止那些投放广告、跟踪用户行为的脚本、恶意软件和其他有害内容的应用程序。由于 Zen 在系统层面运行，因此它可以抵御浏览器扩展程序无法防御的威胁，例如嵌入在桌面应用程序和操作系统组件中的跟踪器。Zen 内置了许多预装过滤器，同时也允许用户轻松添加 hosts 文件和 EasyList 式过滤器，从而根据自身需求定制保护方案。
