  • Native Windows XP, Vista, 7, and 8.x support. The browser runs directly on operating systems from Windows XP through Windows 11, allowing older computers to access modern websites without certificate errors or protocol incompatibilities.
  • Fast vulnerability patching. Critical security fixes are integrated within less than seven days after public disclosure, reducing exposure window to known exploits on outdated systems.
  • Functional security sandbox. The Chromium process isolation sandbox operates fully, protecting the host operating system from malicious code executed through web pages.
  • Customizable tab options. Users can select between trapezoidal tabs (classic style), transparent tabs, or outlined tabs, altering the tab bar appearance according to preference.
  • Manifest V2 support. Unlike Google Chrome, Supermium does not remove support for Manifest V2 extensions, guaranteeing continued compatibility with ad blockers like uBlock Origin and other privacy tools.
  • Google Sync integration. Allows signing in with a Google account to synchronize bookmarks, history, passwords, and extensions across devices, identical to standard Chrome.
  • Widevine CDM support (Windows 7 and later). Includes the Widevine module for DRM-protected content playback on Windows 7, 8, 8.1, and 10 systems for services like Netflix, Spotify Web, and Disney+.
  • GDI font rendering. Activating the #force-gdi flag in chrome://flags enables the Windows GDI rendering engine, improving font sharpness on older system versions.
  • Persistent dark mode on browser UI. The #force-dark-mode flag in chrome://flags forces a dark theme across all browser interface elements including toolbars, menus, and dialog boxes.
  • SSE2-only processor support (32-bit build). The 32-bit compilation works on CPUs supporting only the SSE2 instruction set, such as early Intel Pentium 4 and AMD Athlon 64 processors.
  • Aero Glass style titlebars. On Windows Vista and 7, the browser uses Aero Glass frosted glass titlebars instead of the flat Windows 10 style, maintaining original system aesthetics.
  • Ungoogled-chromium flags integrated. Includes numerous experimental flags from the ungoogled-chromium project, allowing users to disable telemetry, Google services, and other unwanted features.

The development history of Supermium began around 2022, when the primary developer operating under the pseudonym win32ss decided to create a modern Chromium browser for obsolete Windows systems. The project emerged from the necessity to maintain compatibility with computers running Windows XP, Vista, and 7 after Google Chrome officially ended support. The program is written primarily in C++, using the Chromium codebase with specific modifications to restore compatibility with legacy Windows APIs and patch the sandbox. The developers maintain a consistent release cycle, manually applying security patches from the upstream Chromium repository and adapting them for Windows versions not officially supported.
