Voltura HardTop is a free, open-source Windows companion built with C# and .NET 10. Search open windows by title or application and pin them above the rest. Ctrl+Alt+Z opens the picker; Ctrl+Alt+T pins or unpins the active window. Both shortcuts are configurable.
21 languages, light/dark/system themes, app opacity, optional startup with Windows, and a tray menu. Closing the window keeps the app running; exiting restores its own always-on-top changes. No accounts or telemetry.
Self-contained Windows x64 installer and portable ZIP. Installed copies download verified updates and ask before installation. Portable copies use manual downloads. MIT license, copyright Voltura AB.
