@needle-tools/engine/dist/needle-engine.bundle-BuI2pjv1.min.js

Needle Engine is a web-based runtime for 3D apps. It runs on your machine for development with great integrations into editors like Unity or Blender - and can be deployed onto any device! It is flexible, extensible and networking and XR are built-in.
