Sidebar Diagnostics

Sidebar Diagnostics is a free, open-source Windows application that displays real-time hardware monitoring information in a desktop sidebar. It provides continuous visibility into CPU, GPU, memory, network, and storage performance. Users can monitor processor utilization, temperatures, clock speeds, and other supported hardware measurements. The application presents information through customizable text indicators and performance graphs. Its alert system can notify users when selected values exceed configured thresholds. Sidebar Diagnostics supports adjustable positioning, colors, fonts, and keyboard shortcuts. It also includes a desktop clock and high-DPI monitor support, making it a practical utility for monitoring system health without repeatedly opening separate diagnostic applications.
