What sets it apart

A wallpaper that listens to your machine.

Most engines play a loop and stop there. Sucrose reads your audio and your hardware in real time, then gets out of the way the moment you start working or gaming.

01

Sucrose Audio API

A real-time FFT audio visualizer drives compatible web wallpapers off your system audio and music — spectra, pulses and motion that move with the sound.

02

Performance-aware

Auto-pauses when a game or app goes fullscreen, runs a power-saving mode on battery, spans multiple screens and all resolutions, and manages CPU/GPU usage.

03

Sucrose System API

A JavaScript API exposes live hardware and system data straight to web wallpapers — CPU, GPU, RAM, storage, battery, network and BIOS — so a wallpaper can genuinely respond to your machine. A capability still rare among free engines.

Free & open source

The full engine is free on GitHub — no paywall, no payment for any feature, no trial, no watermark. Read the source, file an issue, ship a fix.

Customizable

Many wallpapers expose their own interactive controls — colors, speed, intensity and behavior — adjustable from the app. Or build your own wallpapers from scratch.

The engine layer

Eight engines. Six wallpaper types. One app.

Different content wants a different engine. Sucrose ships a backend for each job and lets you pick — web stacks for interactive pages, dedicated players for video and Gif, and its own native engines.
