Background: DuckDuckGo Browser and Desktop Availability

• DuckDuckGo provides privacy-focused browser apps primarily for mobile platforms (iOS, Android) and privacy-focused extensions/search services for desktop browsers.
• As of April 10, 2026, there is no official DuckDuckGo Browser application specifically distributed as a native desktop browser for Windows (including Windows 8.1) in the same sense as its mobile apps. DuckDuckGo offers browser extensions and privacy tools designed to work within mainstream desktop browsers (e.g., Chrome/Chromium, Edge, Firefox) rather than a separate official portable desktop browser binary.

DuckDuckGo does not offer an official portable version of its browser for Windows 8.1. The official desktop app currently requires Windows 10 (version 1809) or higher. duckduckgo browser download for windows 81 portable
