Supermium is a free and open-source web browser developed by Shane Fournier. It is a fork of Chromium with its main feature being support for old versions of Microsoft Windows that are no longer supported by Chromium; this includes all versions prior to Windows 10, starting with Windows XP. Supermium has other features not supported by Chromium, including the Google Chrome Sync service. The developer plans to introduce features such as Windows 2000 support, WebGPU for D3D9 rendering, and support for Manifest v2 extensions in future versions.
Supermium has 32-bit and 64-bit executables. Its version numbers are parallel with Chromium's.
