It solves the problem of building the popular Oj JSON library on Windows Ruby compiled with MSVC, which the upstream version cannot compile due to POSIX dependencies. The project replaces POSIX code with Windows equivalents and adds SIMD acceleration via MSVC, providing the same API as Oj. It is useful for Ruby developers on Windows needing fast JSON parsing and serialization, especially in Rails apps. Compared to the upstream gem, it offers drop‑in compatibility without requiring MinGW, making Windows development smoother.
