Matrix Rain Effect - Online Falling Code Animation

The Matrix rain effect, also known as "digital rain" or "falling code," is a visual effect inspired by the movie The Matrix. It displays cascading green characters against a black background, simulating code streams. This online tool lets you generate and customize your own falling code animation in real time.

Simply adjust the settings on the right panel: choose a character set, stream color, speed, font size, density, tail length, and background trail opacity. Click Start to run the animation, Pause to freeze it, or Reset to randomize the positions. You can also enter fullscreen mode for a more cinematic experience.

Yes! Choose from presets like Katakana, binary, digits, or letters. You can also select Custom and type your own set of characters. The stream color is fully adjustable using the color picker, and you can even tweak the tail length to change how many trailing characters appear behind the leading bright character.

Absolutely. The entire animation runs in your browser using HTML5 Canvas and JavaScript. No data is uploaded or stored. It’s safe, private, and you can use it for live wallpapers, video backgrounds, or just for fun. Performance is optimized for most modern devices, including mobile.

You can screen‑record the canvas area using any screen capture tool (OBS, QuickTime, etc.). For web backgrounds, you can set the URL of this page inside an iframe or use a browser extension that plays canvas animations. The tool also works well as a live wallpaper via third‑party video wallpaper apps if you record it first.
