Stage & live sets
Build surfaces, save Looks, map MIDI, and move through a cue list without leaving the editor.
Browser-based / open by design
Map anything onto anything.
A free projection-mapping instrument for the browser. Add media, fit it to a real surface, shape the look, and send a clean output to your projector.

The shortest path to light
Three moves between a blank wall and a live image.
01 / ADD
Give the surface a source.
Drop in video or images, start from a shader, use a webcam, or capture a screen. Each surface keeps its own source and treatment.
02 / WARP
Pull the image onto reality.
Drag four corners over the physical target. Perspective-correct homography keeps straight content straight across the quad.
03 / GO LIVE
Move the clean frame to output.
Open a chrome-free output window, move it to the projector display, and keep editing while the live image updates.

Built for physical space
From one strange object to a room full of surfaces.
Generated atmosphere explores where the work can live. The product frames elsewhere on this page are direct captures from Projektor.
Architecture & objects
Fit imagery to walls, columns, props, and irregular polygons with independent surface controls.
Installations
Create a self-contained browser project, open a clean output, and preserve the setup as a file or link.
Creative coding
Write fragment shaders beside the stage, expose parameters, and make them respond to live audio.
One working surface / every control
An instrument, not a black box.
Every source, corner, mask, blend mode, color adjustment, Look, and cue stays visible and editable. Projektor keeps the stage at the center.

MCP / agent control
Let an agent operate the same instrument.
Projektor includes an MCP server for adding surfaces, placing corners, assigning media, adjusting output, and recalling Looks through the real editor runtime.

Before you point it at a wall.
01What is Projektor?
Projektor is free projection-mapping software that runs in your browser. Add an image, video, or live shader, fit it to a physical surface with corner-pin warp, and open a clean output window for your projector.
02Is it really free?
Yes. There is no account, trial timer, or output watermark. Projektor is MIT-licensed, so you can inspect, self-host, and adapt the source.
03What travels in a shared link?
The link stores the project setup — surfaces, transforms, shaders, Looks, and cues. URL-based media travels with it; local files and webcam sources stay on the device that opened them.
04What browser should I use for a show?
Use a recent desktop Chrome or Edge build for the smoothest multi-display Go Live workflow. WebGL2 is required, and a wired second display is the most predictable projector setup.
Output 01 / standing by
There is a surface waiting.
