simple is a simple, fast, complete and extensible JSON encoder/decoder for Python 3.8+ with legacy Python 2.7 support. It is pure Python with an optional C extension for speed, and is the externally maintained development version of Python's built-in library.

Use cases

• serialize and deserialize JSON in Python
• parse JSON strings with custom encodings
• customize JSON serialization for arbitrary objects
• post-process parsed JSON with object hooks
• embed pre-encoded JSON with RawJSON
• get faster JSON performance than the stdlib via C extension
• maintain legacy Python 2.7 codebases needing JSON

When to choose

• you need JSON features or bug fixes not yet in the stdlib module
• you need to support Python 2.7 alongside Python 3
• you need faster JSON encoding/decoding via the optional C extension
• you need extensible serialization with default hooks or object_hooks

When to avoid

• your project only targets modern Python and stdlib meets your needs
• you need a non-JSON serialization format
• you want a zero-maintenance dependency-free solution
