Single Engine vs Multi-Product

Apryse compiles one C++ core to every platform, ensuring synergies persist when leveraging multiple features. Aspose maintains independent libraries per product (Words, PDF, Cells, etc.) with separate .NET and Java implementations. Each API is internally consistent, but shares no common patterns with sibling products
