A browser alternative to TouchDesigner for audio-reactive visuals
TouchDesigner is a node-based environment where you build the visual yourself. If you want the result rather than the patching, BLOOB and Galaxy hand you forty-seven finished audio-reactive scenes that already lock to the beat — free, in a tab.
Who this is for
- People who bounced off node graphs
- Creators who need a visual today, not a project file
- Anyone on a machine that will not run a heavy runtime
Different tools, different jobs
TouchDesigner can build anything: custom geometry, shaders, sensors, multi-machine output, hardware integration. It also costs time to learn and, commercially, money. BLOOB builds nothing — it gives you finished scenes that already respond to kick, snare, hats, spectrum and song structure, which is a different trade.
The reactive part is already solved
Separate onset detection per band, a beat grid predicted slightly ahead of the audio, automatic compensation for your output latency, and a whole-track structure map that fires scene changes on real section boundaries. That is precisely the part a first TouchDesigner patch spends a weekend getting almost right.
How far you can shape it
Scene, mood, palette, intensity, glow, trails and particle density are all controls; MIDI learn binds them to a hardware controller; presets, share links and .bloob files save a look; and both apps embed chrome-free in an iframe if you want the visual inside your own page.
How to do it
- Open BLOOB for 2D scenes, or Galaxy for WebGL 3D
- Feed it a file, a microphone, an instrument through an interface, or a browser tab
- Pick a scene and shape it with the mood, palette and intensity controls
- Record live, or export offline at up to 4K
Questions people ask about touchdesigner alternative
Can I write my own shader?
No. The scenes are fixed — though there are forty-seven of them across the two apps, and each one reacts to a different part of the sound.
Does it output NDI or Spout?
No. Capture the tab in OBS as a browser source, or export a file.
Is it GPU heavy?
BLOOB is Canvas2D and runs on almost anything. Galaxy is WebGL and wants a real GPU for the heaviest scenes.
What does it cost?
Nothing, with no commercial restriction and no watermark.
