Phaselight
Mix GPU shaders, 3D dioramas, fluid, projection shapes and live media on a clip grid — with cue/take staging, audio reactivity and MIDI. Then stream it anywhere.
One instrument, every surface
A whole VJ rig on a clip grid
Columns are looks, rows are layers. Stage a change on the CUE deck, then commit it with TAKE — instant, crossfaded, or A/B swap. The audience never sees you work.
100+ GPU shaders
A deep built-in library plus your own GLSL — image-sampling, generative, kaleidoscopic, all live.
3D dioramas
glTF scenes with rigged characters and cinematic staging — the Menagerie beings, Icarus and more.
Fluid & particles
Real-time fluid simulation and particle fields that react and flow with your set.
Projection shapes
HeavyM-style outlines & fills over shared layouts — trace a venue once, switch looks live.
Audio-reactive
Envelopes, beats and a full spectrum drive any parameter — the visuals move with the music.
MIDI & mods
Learn any controller to any control, plus 16 macros driven by LFOs and audio via route-learn.
See it move
Built like an instrument, not a slideshow
Cue, take, perform
Columns are looks, rows are layers. Dual preview shows staged vs. live at all times. Per-cell FX racks, HITS gestures for drops, undo/redo, panic and fade-to-black — mistakes stay recoverable mid-set.
Put it on a clock
A beat-quantized column sequencer with per-row lanes and BPM transport — tap tempo or lock to MIDI clock. Trigger looks in time and let the set run itself while you ride the highlights.
Sixteen LFOs, unlimited targets
Up to 16 LFOs — each assignable to an unlimited number of targets — plus audio envelopes, beats and a full spectrum. Route-learn any parameter in a click and the whole rig breathes on its own.
Trace the room, once
Vector tools, snap and mirror, background tracing over an image, webcam or the live output — and one-click auto-trace that turns image contours into shape layouts.
How a set flows
Three moves, endlessly
Cue the next look
Build the next moment on the CUE deck — pick engines, dial FX, arm a HITS gesture. It stays private on the preview pane.
Commit on the beat
Hit TAKE to push it live — instant, crossfaded or A/B swap. The sequencer can fire it for you, quantized to tempo.
Send it everywhere
Your composite goes out as a virtual camera, over NDI, or to a clean second display — straight into OBS, a projector, or the wall.
Get it out of the box
Made for livestreaming & stages
Phaselight shows up as a webcam and streams full-framerate over the network — no capture-card gymnastics. Drop it straight into your broadcast.
Core vs Pro
Everything to perform, free
The whole instrument lives in the free Core tier. Pro adds the broadcast outputs — and right now it costs nothing.

The Core tier is free — the full instrument and live visuals. A beta key unlocks Pro outputs (NDI, virtual camera) and is free during the beta. We hand keys out to testers one at a time.
