What RainbowTaskbar is

RainbowTaskbar is a free Windows app for changing how the taskbar looks and behaves. Configurations can use animations, colors, images, websites, and other effects, and can be built either for the web or through instructions. Web configurations support mouse interaction, WebGL, canvas graphics, and video; they can also use the RainbowTaskbar API to change taskbar style and transparency. The app supports taskbar positioning and transparency controls, along with complex multi-monitor arrangements that may involve scaling and positioning. Its Workshop lets users share and download configurations. Downloading does not require an account, while uploading requires signing in with Google or GitHub. The app is portable, but requires the .NET 8 runtime if it is not already installed. The maker warns that RainbowTaskbar conflicts with TranslucentTB and says to close TranslucentTB before running it. The maker describes it as a passion project first released in 2021 and says users can support future development by buying the Microsoft Store version or donating through PayPal.
