It benchmarks as the fastest Python library for JSON and is more correct than the standard json library or other third-party libraries. It serializes dataclass, datetime, numpy, and UUID instances natively. orjson.dumps() is something like 10x as fast as json , serializes common types and subtypes, has a default parameter for the caller to specify how to serialize arbitrary types, and has a number of flags controlling output. orjson.loads() is something like 2x as fast as json , and is strictly compliant with UTF-8 and RFC 8259 (\"The JavaScript Object Notation (JSON) Data Interchange Format\"). Reading from and writing to files, line-delimited JSON files, and so on is not provided by the library. orjson supports CPython 3.10, 3.11, 3.12, 3.13, 3.14, and 3.15. It distributes amd64/x86 64/x64, i686/x86, aarch64/arm64/armv8, and armv7 wheels for Linux, amd64 and aarch64 wheels for macOS, and amd64, i686, and aarch64 wheels for Windows. Wheels published to PyPI for amd64 run on x86-64-v1 (2003) or later, but will at runtime use AVX-512 if available for a significant performance benefit; aarch64 wheels run on ARMv8-A (2011) or later. orjson does not and will not support PyPy, embedded Python builds for Android/iOS, or PEP 554 subinterpreters. orjson may support PEP 703 free-threading when it is stable. Releases follow semantic versioning and serializing a new object type without an opt-in flag is considered a breaking change","default_branch":null,"files":null,"tree":[],"storefront":"/r/ijl","claimed":false,"request_supported":{"post":"https://gitbuyer.com/r/ijl/orjson/request-supported","requests":0},"note":"indexed from public GitHub; nothing is for sale on this page.
