Mapsicle is a high-performance, modular object mapping ecosystem for .NET. Choose only what you need:
See it working: github.com/arnelirobles/mapsicle_samples maps one e-commerce order aggregate through Mapsicle, AutoMapper and Mapperly side by side, in a CRUD API over SQLite, with an endpoint that reports where the three disagree. Declare a pair and Mapsicle matches hand written code on that graph: 287.7 ns against 288.5, allocating the same 1.41 KB. Mapperly and Mapster are 1.08 and 1.09.

The core
Mapsiclepackage has zero dependencies. Extension packages introduce their respective third-party dependencies (listed in the table above).
Zero configuration by default. Configure only where a mapping is genuinely not conventional.
