LED AppBar pins a scrolling LED dot-matrix ticker to the very top edge of your Windows desktop ā not as a floating window, but as a real Windows AppBar via SHAppBarMessage. That means maximized windows respect the bar's space instead of overlapping it, exactly like the taskbar. Point it at any URL: RSS news, clocks, Twitch chat, scrolling illustrations, whatever renders in a browser. Built with Tauri (Rust + WebView2). Multi-monitor support, auto-hides on fullscreen, ~4 MB installer.
Hey Product Hunt! š
Maker here. I built LED AppBar because I wanted something gently
moving at the edge of my screen while I work ā a little piece of
ambient info (news, RSS, a clock) that didn't steal a whole browser
tab or cover my windows.
Every "ticker bar" I tried was just an always-on-top floating window
that fought with my maximized apps. So I went and implemented it
properly: LED AppBar registers itself with Windows as a real AppBar
via SHAppBarMessage ā the same mechanism the taskbar uses ā so
maximized windows automatically respect its space.
What's inside:
- Tauri (Rust + WebView2) for a ~4 MB installer
- A ~22,000-glyph bitmap font atlas for the LED dot-matrix rendering
- Real AppBar integration (not always-on-top)
- Multi-monitor, 5 height presets, auto-hides on fullscreen
- Point it at any URL ā RSS, clocks, Twitch chat overlays, cute
illustrations, whatever renders in a browser
It's open source under MIT:

And it's pay-what-you-want on itch.io (suggested $2):

I'd love feedback on:
- Other widget ideas (what would you put in the bar?)
- Anything weird with AppBar behavior on your setup
- Whether this should eventually come to macOS / Linux
Thanks for checking it out! I'll be here all day answering questions.
