## What it is
json-c is a C library implementing a reference-counted object model for constructing, serializing, and parsing JSON, aiming to conform to RFC 8259. It builds with CMake across Unix, Windows, Android, and other platforms.

## Use cases
- parse json in c
- generate json strings from c objects
- embed json support in a c application
- read and write json config files in c
- conformant rfc 8259 json parser for c

## When to choose
- you need JSON parsing or serialization in C or C++
- you want a mature, widely packaged C JSON library
- you need cross-platform builds including Android and embedded targets

## When to avoid
- you are working in a higher-level language with native JSON support
- you need streaming or SAX-style parsing rather than a DOM object model
- you need strict license clarity, as the license is non-standard

## Facets
- artifact type: library
- maturity: stable
- function: serialization, parser, json
- domain: developer-tools, parsers, apis
- platform: c, windows, cross-platform, embedded
- tags: json-parsing, reference-counting, rfc-8259, cmake, linux, macos
