在當今這個瀏覽器分頁無盡且不斷數位多工的時代，要保持專注比以往更困難。因此，特定網站瀏覽器（SSB）變得越來越受歡迎——它們可以把任何網站變成專用的、無干擾的桌面應用程式。無論你想要獨立的 Gmail 應用、同時運行多個 Slack 或 Notion 帳號，或是把工作與個人應用分開，SSB 都能幫助提升生產力並減少混亂。
在 macOS 與 Windows 上有這麼多工具可供選擇，該如何挑選？本指南說明什麼是 SSB、探討它們為何有用，並比較頂級工具：WebCatalog Desktop、漸進式網頁應用（PWA）、Coherence、Unite、Fluid、Boxy Suite 與 Flotato。我們也會說明為何對大多數使用者來說，WebCatalog Desktop 是最通用且功能豐富的選擇。
什麼是特定網站瀏覽器（Site-Specific Browsers）？
特定網站瀏覽器是專門的應用程式，用來在獨立視窗中開啟單一網站（或網頁應用程式）——不會被分頁、書籤或瀏覽器介面干擾。SSB 讓網頁應用看起來像原生桌面應用，能讓你在不同視窗中執行多個帳號、維持工作與個人環境的分離，並透過隔離資料與 Cookie 提供更好的隱私保護。
為什麼要使用特定網站瀏覽器？
SSB 提供幾項主要好處：
- 以獨立、類應用程式的視窗幫助你專注
- 允許多重登入與帳號切換
- 與作業系統整合（通知、Dock/工作列、快捷鍵）
- 透過沙盒與 Cookie 分離改善隱私
- 提供自訂化、廣告阻擋與離線存取選項

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
2. Progressive Web Apps (PWAs)
Platform Support: macOS, Windows, Linux, ChromeOS
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.

3. Coherence
Platform Support: macOS only
Coherence lets you build SSBs using Chrome, Brave, Edge, or Opera as the engine. It supports browser extensions, single or multi-tab modes, and advanced URL handling. While it benefits from Chrome's stability, the team doesn't have full control over the underlying browser, which can affect performance and customization.
Pros:
