Engineers discount names that sound invented and trust ones that sound like something they’d find in a codebase. This is firmly the latter.
A render cache stores the output of expensive rendering work so it doesn’t have to be redone, and the pattern appears everywhere: page generation, 3D and video production, map tiles, data visualisation.
That makes it a strong name for an edge or CDN product, a rendering service, a static site infrastructure company, a 3D pipeline tool, or a performance consultancy. The rendering farm reading deserves separate mention, since 3D and VFX rendering is a large compute market with its own providers.
