A benchmark suite evaluating the conformance and performance (speed, memory, code size) of 41 open-source C/C++ JSON parsing and generation libraries. It tests compliance with RFC7159/ECMA-404 standards and measures parse/stringify performance.

Use cases

• compare performance of C++ JSON libraries
• check JSON parser conformance against RFC7159
• find the fastest JSON parsing library for C++
• benchmark memory usage of JSON parsers
• evaluate JSON roundtrip correctness
• optimize a JSON library using benchmark results

When to choose

• you need to select a C/C++ JSON library based on measured speed, memory, or standards conformance
• you are developing or optimizing a JSON parser and want objective comparison data

When to avoid

• you need a JSON library itself rather than a comparison of libraries
• you work in languages other than C/C++
• you need up-to-date results for recently released libraries, as the benchmark was last updated in 2022
