KVRNL is an independent software studio that makes free-to-use Windows desktop apps: CLI Assistant (desktop companion for your AI coding CLIs), CarbonCopy (real-time folder backup for Windows), Master Keybind Chart (every shortcut, one place), Synthesize Me (browser-free music sequencer & synth), AdGenie (design studio for content creators), Turnstyle (DJ turntables for your desktop), Immersion (audio-reactive OBS overlays for streamers), Clip Lab (cut clips out of long recordings, instantly), Easy NVidia Updater (NVIDIA drivers, always up to date — quietly), Kernel (a fast, GPU-accelerated Windows terminal), Mainframe (a wall of remote desktops) and FitMaker (custom FiveM clothing, no Blender needed). Every app is free under a personal license — a free account issues your license key, and the apps update themselves.

Is it really free?

Yes — every KVRNL app is free to use under a personal license. No trials, no feature gates, no subscriptions, ever.

Why do I need an account and a license key?

The apps are free but not open source. A key from your free account keeps your copy yours, unlocks silent updates, and lets you re-download anytime from your account.

What data do you collect?

Only what we need to run KVRNL: your account email, your license keys, and some usage and security data that helps us fix bugs, improve the apps and stop abuse. We never sell it, and logs are deleted automatically after 12 months. The privacy policy has the details.

Which platforms are supported?

Windows desktop today. Once installed, every app updates itself silently so you always have the latest version.

Can I use one key on more than one computer?

A key binds to one machine at a time. You can release it from your account and move to a new computer whenever you like.
