在当今这个浏览器标签页无穷无尽且不断进行数字化多任务的时代，保持专注比以往任何时候都更难。正因为如此，站点专用浏览器（SSB）越来越受欢迎——它们可以将任何网站变成专用的、无干扰的桌面应用。无论你想要一个独立的 Gmail 应用、运行多个 Slack 或 Notion 账号，还是将工作和个人应用分开，SSB 都能帮助提高生产力并减少混乱。
在 macOS 和 Windows 上有这么多工具可选，如何挑选合适的？在本指南中，我们解释什么是 SSB，探讨它们为何有用，并比较主要工具：WebCatalog Desktop、渐进式网页应用（PWA）、Coherence、Unite、Fluid、Boxy Suite 和 Flotato。我们还会重点说明为什么对大多数用户来说 WebCatalog Desktop 是最通用、功能最丰富的选项。
什么是站点专用浏览器？
站点专用浏览器是专用应用，可在一个独立窗口中打开单个网站（或网页应用）——没有标签页、书签或令人分心的浏览器界面。SSB 让网页应用更像原生桌面应用，允许你在独立窗口中运行多个账号，保持工作和个人场景的组织，并通过隔离数据和 cookie 提供更好的隐私保护。
为何使用站点专用浏览器？
SSB 提供若干关键优势：
- 用类似应用的孤立窗口帮助你保持专注
- 允许多重登录与账号切换
- 与操作系统集成（通知、Dock/任务栏、快捷键）
- 通过沙箱和 cookie 分离提升隐私
- 提供自定义、广告拦截和离线访问选项

With so many tools available across macOS and Windows, how do you choose the right one? In this guide, we explain what SSBs are, explore why they’re useful, and compare the top tools: WebCatalog Desktop, Progressive Web Apps (PWAs), Coherence, Unite, Fluid, Boxy Suite, and Flotato. We'll also highlight why WebCatalog Desktop stands out as the most versatile and feature-rich option for most users.
What Are Site-Specific Browsers?
A site-specific browser is a specialized app that opens a single website (or web app) in a dedicated window—free from the clutter of tabs, bookmarks, or distracting browser UI. SSBs make web apps feel like native desktop apps, allow you to run multiple accounts in separate windows, keep your work and personal contexts organized, and offer better privacy by isolating data and cookies.
Why Use a Site-Specific Browser?
SSBs offer several key benefits:
- Help you focus with isolated, app-like windows
- Allow multiple logins and account switching
- Integrate with your OS (notifications, dock/taskbar, shortcuts)
- Improve privacy through sandboxing and cookie separation
- Provide options for customization, ad blocking, and offline access
1. WebCatalog Desktop
Platform Support: macOS, Windows, Linux
WebCatalog Desktop offers a powerful cross-platform SSB experience with built-in support for thousands of web apps. It includes advanced workspace features like spaces and subspaces for organizing multiple accounts, privacy-focused sandboxing, and cloud sync to keep your apps in sync across devices. WebCatalog also provides ad-blocking, password or Touch ID protection, and custom app icons.
Pros:
- Cross-platform (Mac, Windows, Linux)
- Cloud sync
- Spaces and subspaces for multi-account management
- Built-in app catalog with deep customization
- Secure sandboxing and ad/tracker blocking
Cons:
- No browser extension support
- Free version has app/space limits

Progressive Web Apps (PWAs) offer the most lightweight SSB approach, built directly into most modern web browsers, including Google Chrome, Microsoft Edge and Mozilla Firefox. They allow users to install supported web apps as desktop-like apps, with basic OS integration and some offline capabilities. Users can install PWAs directly from the browser, adding them to their desktop or home screen without needing to visit an app store.
