We build tiny 3D planets you can play in a click. No downloads, no installs. Just open a world and step in.
Every world is its own tiny planet with its own rules. New branches grow on the tree every so often.
Ride the dunes as a giant sandworm on a tiny desert planet. Answer the thumpers, carry riders, swallow harvesters.
Next branch: a little water planet. Details soon.
A mossy planet under a giant tree. Still a seed.
Every world runs straight in the browser, on desktop, phone and tablet.
Whole worlds small enough to hold in one view, full of life up close.
Real-time 3D on the open web, rendered with WebGPU where your device supports it.
One day you'll be able to put on a headset, step onto these planets and meet friends there. We're not there yet, but every world is being built with it in mind.
In the worksThreehouse is a one-person studio making small, handcrafted 3D worlds for the web. Like a treehouse, it's a place you climb up to, a bit hidden, a bit magical, and always growing.
The name is a nod to three.js, the open-source 3D engine every world here is built on.
