// a boot manager for this decade
Boot with the power of GRUB,
with the looks of the future.
A minimal, fast, graphical UEFI boot manager written in C. One ~340 KB binary. No dependencies. Just a config file and your imagination.

// the good stuff
Everything built in.
Nothing bolted on.
A menu that actually looks good
Double-buffered, flicker-free, animated. Frosted-glass highlights, wallpaper-matched Material accent colors, GIF + MJPEG MP4 + compact VBG wallpapers, themes, live clock, screensaver, mouse and touch — your boot screen finally matches your rice.
Zero-config
Delete boot.conf and Visor still finds Windows, UKIs, and kernels — and derives a correct root= cmdline by itself, btrfs flags included.
Live USB hotplug
Plug a stick in while the menu is open — it animates in. Pull it out — it slides away. No other boot manager does this.
File browser
Press B to browse every readable volume and boot any kernel, initrd or .efi straight from the menu.
Encrypted boot
Kernel and initrd live encrypted on the ESP. One password decrypts them and unlocks your LUKS root.
Btrfs snapshots
Browse snapper and Timeshift snapshots in the menu and boot one, once. Rescue without a live USB.
Secure Boot aware
Verifies through shim, refuses unverifiable images, and tells you exactly why the firmware said no.
Live clock
Firmware-RTC clock that ticks without redrawing the whole menu — position, 12h/24h, seconds, date, frost and shadow, header-aware. Keep it on the screensaver if you like.
Screensaver
Idle dim to background + clock, then blank to black — wakes on any key or pointer. Animated wallpapers idle while blanked.
Measured boot
TPM2 PCR 5 for boot.conf, PCR 12 for the cmdline, plus Boot Loader Interface (Loader*) for bootctl / bless-boot.
Debuggable
Every step logs one line. Failed boots land in a recovery console, not a black screen.
// one menu, any wallpaper
Animated or not, it matches.
// engineered, not decorated
Small. Fast. Responsive.
Written in C
Freestanding, zero external dependencies, fixed-point math only — no float, no libm, no runtime to break. BSD-2 licensed.
Fast
Power button to menu in about a second, even with filesystem drivers installed — they load lazily, you don't wait.
Tiny & responsive
One binary on your ESP. GPU-direct rendering with write-combined framebuffers; input never lags, animations never stutter.
// in numbers
Six weeks old. Already loved.

Your boot screen, only prettier.
