SpeedTray is a free, lightweight internet speed meter for Windows 10 and Windows 11. It displays real-time download and upload speeds directly on the taskbar, automatically switches between Kb/s and Mb/s, follows the Windows dark or light theme, and runs as a portable standalone EXE.
The latest version is available on the GitHub Releases page:
