GlowtropeVisuals that move with your music

Layer audio-reactive visualizations, shape them with the beat and the melody, and run a live show across every screen you have. It all runs in your browser.

Live shows

Keyboard shortcuts

🎧

Any music

Play files or whole folders, listen through a microphone, or capture a browser tab — Spotify, YouTube, SoundCloud. It finds the beat, the song's sections and even the melody.

🌌

Over 70 visualizations

Spectrum analysers, endless fractal zooms, a ray-traced black hole, Saturn, laser shows, Vegas light walls, fluid simulations, Escher tilings and more — plus your own shaders.

🎨

Layers with their own look

Stack up to six visualizations. Give each one its own palette and effects, or share them across the whole picture.

〰️

Everything can move

Make any control swing on the beat, or tie it to the bass, the melody, an LFO or a MIDI knob.

🎛️

Built for live shows

Prepare the next look in preview while the screens stay live, then cut, fade or ride the T-bar. Fades can overlap. Banks, favorites and hotkeys keep everything one key away.

🖥️

Every screen

Mirror to projectors or tile one picture across a video wall, and record the show to a video file.

Private by design

There's no account and nothing to install. Your music is analysed on your own device and never uploaded; presets and settings stay in your browser. Share links carry the look itself, in the part of the address that is never sent to a server.

How these docs are organised

Start here walks you through your first few minutes.
The guides (left) explain each part of the app and how to use it, from finding the beat to running a show.
Reference lists every keyboard shortcut, setting, visualization, effect and modulation source. These pages are generated from the app itself, so they always match it.
