This is a modern C++, free, tiny, simple and one-header JSON library. You are welcome to use it freely in commercial projects. The tests are designed for Linux but can be adapted for any platform with gtest/gmock support and a modern compiler available.
Here are some examples. Their source files can be found in the 'examples' directory.
