Pick Your Hacker Typer Language
Every fake coding screen on HackerTyping, one page each: the typer opens preloaded with that language's sample, plus presets for Matrix rain, retro CRT, and auto-typing demo mode. Mash any keys and look fluent in all of them — nothing is executed, and nothing you press is recorded.
HackerTyping is visual entertainment. It does not hack, scan, connect, or execute code.

Beyond the languages
The main hacker typer defaults to C++ and switches languages in one click. For other screens, try the Matrix rain screensaver, the AI agent simulator, or the prank pack: fake update, fake blue screen, and fake virus scan. Filming something? Read the filmmaker guide.
