Open Brush lets you paint in 3D space with virtual reality.

Unleash your creativity with three-dimensional brush strokes, choosing from a wide palette, of brushes, including stars, light, and even fire. Your room is your canvas. Your palette is your imagination.

The possibilities are endless.


Open Brush is a community-led evolution of Tilt Brush, a room-scale 3D painting XR application, now available for free.

A huge thank you to the Tilt Brush team and Google for making this open source, especially Patrick Hackett!

Since the initial release, Open Brush has added several significant features; see a full list of changes between Tilt Brush and Open Brush for more details.


We started development on the Icosa platform after learning Google was shutting down its Poly platform, which allowed creators to share and remix works created in Google Blocks and Tilt Brush. We felt it was important to preserve and maintain such an important resource that many artists depend on for their livelihoods.


Open Brush strives to be an open source tool to help everyone create their own art. We believe in the preservation of art, and the freedom of artists.

At our core, we are community led and driven, and while there may be a small core team behind Open Brush, it would not be possible without our community.

Open Brush is, and always will be, open and free.
