Do More with Heathen

Battle Tested Products

Every Heathen product is born from practical need.

Heathen Engineering is the software engineering unit in Heathen Group and responsible for creating the technology and tools that enable us to deliver on our clients needs and create the worlds and experiences of our designers’ dreams.

When we create something, we feel might better the lives of our fellow indie developers we test it for abstraction. This means every tool, asset, and content pack we release started life as a practical internal tool rooted in real world use.

Content to kickstart your project

Over the years we have built a few libraries of common content we often use either as is for common uses cases or as the foundation for bespoke content.


Heathen’s UI Kits are big collections of those common icons, images, and assets you need to get your project going with full source included and tooled for easy modification.


The same full source access, dedicated support and frequent updates that make our coded asset products so valuable applies to our content assets as well.
