Kiwi Schema

Kiwi Schema is a schema-based binary serialization format for encoding hierarchical data efficiently. Version 0.5.0 is current, with no established release cadence. It compiles schemas to optimized JavaScript code for encoding and decoding, aiming to be smaller and faster than JSON for structured data. Unlike Protocol Buffers or FlatBuffers, Kiwi is focused on tree-shaped data and JavaScript-first usage.
