Sidebar Diagnostics for Windows

Brief overview

Sidebar Diagnostics is a free, open-source utility by ArcadeRenegade that displays vital hardware and system metrics along a slim panel on your desktop. It’s built to be a simpler, more visually pleasing alternative to built-in Windows tools like Task Manager and Resource Monitor, and it behaves similarly to lightweight tools such as CPU-Z and Rainmeter.

Installing and first-time setup

Installation is fast and unobtrusive. During the first launch an Initial Setup wizard guides you through the minimal configuration steps. After setup, the app runs in the background and places a compact information panel on your screen while an icon sits in the system tray for quick access.

Personalization options

You can tailor the sidebar extensively to match your workflow and desktop style. Customizable elements include:

• Enabling the widget to launch at system startup
• Choosing the date and clock display formats
• Forcing the panel to stay above other windows
• Assigning custom keyboard shortcuts for showing, hiding, reloading, or closing the interface
• Allowing click-through interaction so clicks pass to underlying windows
• Adjusting the UI scale to suit different monitor sizes
• Tuning opacity levels for translucency
• Picking fonts and text sizes
• Selecting a background color or theme
• Positioning the panel on the left or right and changing its width

What it displays

The sidebar presents real-time information about the key components of your PC. Monitored items include:

• Network throughput and connection status
• Graphics card (GPU) details and usage
• Storage devices / logical drives and their activity
• RAM usage and memory statistics
• CPU load and temperature readings (where supported)

Why use it

Sidebar Diagnostics makes ongoing system monitoring effortless by surfacing important metrics in a compact, always-visible format. It’s lightweight, easy to configure, and offers deep personalization so you can keep an eye on performance without constantly opening separate utilities. Whether you work with many windows open or simply prefer a cleaner way to monitor resources, this tool puts the information you need where you can see it at a glance.
