json.h
A single-header JSON parser for C and C++ that performs a single allocation for the entire DOM.
What is json.h?
json.h is a single-header JSON parsing library for C and C++. It reads JSON strings and constructs a read-only Document Object Model (DOM) using only one memory allocation, making it fast and resource-efficient. It solves the need for a simple, dependency-free JSON parser in native applications.
C and C++ developers working on embedded systems, game engines, or performance-sensitive applications where a lightweight, no-dependency JSON parser is required.
Developers choose json.h for its minimal footprint, ease of integration (single header), and efficient single-allocation design. It offers extended JSON5 support without sacrificing simplicity or portability.
