EnfinitOS publishes a per-substrate render SDK for each substrate that ships a visible surface. Each one composes Renderer Core and adds substrate-specific constraints, adapters, and conventions.
Publish at launch. All render substrate SDKs listed here publish at the April 2027 production launch. Sandbox access is available now at enfinitos.com/apply.
