RainbowTaskbar
What it is
RainbowTaskbar is a free Windows app for personalizing the taskbar with animations, colors, images, websites and other effects. Users can configure it through web configurations or instruction-based configurations. Web configurations support mouse interaction, WebGL, canvas graphics and videos, and can use the RainbowTaskbar API to change taskbar style and transparency, among other settings. The app supports complex monitor setups, including scaling and positioning, as well as taskbar positioning and transparency controls. Its Workshop lets users share or download configurations. Downloading does not require an account, but uploading requires signing in with Google or GitHub. RainbowTaskbar is portable and requires the .NET 8 runtime if it is not already installed. The maker warns that it conflicts with TranslucentTB, which should be closed before running RainbowTaskbar. The maker describes it as a passion project first released in 2021. The app is free and open-source, with its listed plan priced as free.
