A minimal, header-only JSON library for C++11 providing parsing, serialization, and intuitive value semantics.
json11 is a tiny, header-only JSON library for C++11 that provides parsing and serialization of JSON data. It solves the problem of handling JSON in C++ projects with a minimal, dependency-free implementation that leverages modern C++ features like initializer lists and value semantics.
C++ developers working with C++11 or later who need a simple, lightweight JSON library for configuration, data exchange, or serialization without external dependencies.
Developers choose json11 for its extreme simplicity, single-header design, and seamless integration with modern C++ idioms, offering a clean alternative to larger JSON libraries while maintaining full functionality.

Single-header implementation eliminates build dependencies, making integration straightforward and keeping the project lightweight, as emphasized in the README.
Leverages C++11 initializer lists for concise JSON object and array creation, shown in examples like Json::object and Json::array for natural code.
Provides methods like string_value() and int_value() for safe value extraction, reducing runtime errors compared to dynamic access in other libraries.
Allows automatic conversion of user-defined types with a to_json method, simplifying serialization as demonstrated with the Point class example.
Lacks advanced JSON features such as Schema validation, JSON Patch, or support for extensions like JSON5, which are common in more comprehensive libraries.
Header-only design can increase compilation times when included in multiple translation units, unlike compiled library alternatives that optimize build performance.
The README is brief, and users often need to inspect the header file directly for detailed usage, which can be a barrier for complex or edge-case scenarios.
