Matrix rain — also called digital rain or falling code — is the cascading stream of glowing green characters made famous by The Matrix films. The original effect used mirrored half-width Japanese katakana mixed with numerals, drawn brightest at the head of each falling column and fading toward the tail. This simulator recreates that look in your browser with a real-time canvas animation — no download, no install.
The on-screen code in the films is commonly matched to a phosphor-style green around #00FF41, with brighter heads near #CCFFCC on a pure black background. If you're building your own theme, grab copy-ready values from our cyberpunk & terminal color palettes.
The page works well as a streaming or video backdrop: add it to OBS as a browser source, or fullscreen it on a second monitor as a stand-in live wallpaper. The streaming toolkit covers the exact OBS workflow. For variations on the theme, try the binary rain generator (0/1 or your own text falling), or pair it with the fake hacker terminal for a full hacker-movie setup.
