Rapidly Build Interactive 3D Apps for the Web

Threlte is a Svelte library that simplifies creating 3D apps for the web. It provides a declarative, type-safe, reactive and interactive API out-of-the-box.

Threlte's 3D rendering is powered by Three.js, and it also provides a physics engine through Rapier and an animation studio via Theatre.js; see packages for details.
