simdjson
A high-performance C++ JSON parser that uses SIMD instructions to parse gigabytes of JSON per second.
What is simdjson?
simdjson is a high-performance C++ JSON parsing library that uses SIMD instructions and microparallel algorithms to parse JSON at gigabytes per second. It solves the performance bottleneck of JSON parsing in servers and data-intensive applications by offering full validation with unprecedented speed.
Developers and engineers working on high-performance servers, data processing pipelines, databases, and applications where JSON parsing is a critical performance factor, such as in Node.js, ClickHouse, and other data-intensive systems.
Developers choose simdjson for its unmatched parsing speed—4x faster than RapidJSON—while maintaining full JSON and UTF-8 validation, automatic CPU optimization, and easy integration with no configuration needed.
