- **Fast**: `yyjson` is several times faster than the builtin JSON module, and

  is [faster than most other JSON libraries][fast].

- **Flexible**: Parse JSON with strict specification compliance, or with

  extensions such as comments, trailing commas, Inf/NaN, numbers of any size,

  and more.

- **Lightweight**: `yyjson` is a lightweight project dependency with low

  maintenance overhead. It's written in C, and has no dependencies other than

  a C89 compiler. Built wheels are between 50kb and 800kb depending on the

  platform.

- **Portable**: Binary wheels are available for many versions of Python

  on many architectures, such as x86, x86_64, ARM, and ARM64, PowerPC, IBM Z,

  and more. PyPy is also supported. Supports Python 3.9 and newer.

- **Manipulate documents**: The fastest JSON Merge-Patch (RFC 7386), JSON Patch

  (RFC 6902), and JSON Pointer (RFC 6901) implementations available for Python

  allow you to manipulate JSON documents without deserializing them into Python

  objects.

- **Traceable**: `yyjson` uses Python's memory allocator by default, so you can

  trace memory leaks and other memory issues using Python's built-in tools.
