This C++ library uses SIMD instructions to parse JSON at multi-gigabyte per second speeds. It claims to be four times faster than RapidJSON and twenty-five times faster than JSON for Modern C++. The library validates UTF-8 strictly and selects the optimal CPU parser at runtime without requiring manual configuration.

It is a strong choice if you are building high-throughput C++ services and already work with large JSON payloads. The main catch is that it requires a 64-bit system and a modern compiler, which excludes older 32-bit environments. If you are working in Python or JavaScript, you will need to check for specific language bindings instead of using the core C++ API directly.
