no Build restrictions with the developer SDK

Developers no longer have to worry about key architecture and multi-platform video playback thanks to our powerful Unity SDK and video infrastructure.

XR Unity SDK

A CMS for all your Unity video apps

The Unity game engine is excellent for developing games, but less for apps that need continuous updates of content since they always require app updates. By hooking up the Headjack CMS to your Unity project, you can always push fresh videos to your app in real-time.

Start crafting your own fully branded experiences from scratch

With our suite of integration tools, it's now super easy to hook up the Headjack CMS to the widely popular Unity Game Engine. Headjack can serve as your rock-solid back end for more complex or custom video apps. On top of that, you don't need to worry about SDK integrations or video playback since we already laid the groundwork for you as a developer.
