Needle Cloud and Needle Engine can be used independently, but they are designed to work together seamlessly.

• Needle Cloud is a web service used to host, optimize, and share 3D assets and apps made with Needle.
• Needle Engine is the runtime and tooling, with integrations into Unity and Blender, used to create rich, interactive 3D web apps.

3D assets uploaded to Needle Cloud can be linked into apps made with Needle, and into other realtime applications. Apps made with Needle can be hosted in Needle cloud.
