anyjson
Wraps the best available JSON implementation available in a common interface

No. The package is abandoned (last release 2012-06-22) and targets obsolete Python versions (2.4–3.1). Modern Python includes a robust built-in json module that eliminates the need for a wrapper. Install friction is high and compatibility with current Python versions is unverified.

Before you install
- Package targets Python 2.4–3.1 and is not maintained for modern Python versions; compatibility with current Python releases is uncertain.
- High install friction due to source distribution format.
- The package is abandoned—last release was 2012-06-22—and no longer maintained.

What it is and what it does
Anyjson is a JSON library wrapper that was designed to automatically detect and use the fastest available JSON implementation on a system, presenting a uniform API regardless of which backend is installed. It provides serialize() and deserialize() functions that work consistently across different JSON libraries, with standardized exception handling (TypeError for non-JSON-serializable objects, ValueError for invalid JSON).
The package is now obsolete. Modern Python includes a built-in json module that is fast and stable, eliminating the need for a wrapper layer. The package has been abandoned since its last release on 2012-06-22 and receives no maintenance or updates. It was originally part of the carrot project and targets only Python 2.4–3.1, making it unsuitable for current development.
Use it for
- Legacy codebases written for Python 2 that depend on anyjson and cannot be easily refactored to use the built-in json module
- Projects that require runtime selection between multiple JSON backends for performance tuning on specific systems
- Code that needs consistent exception types across different JSON library implementations

Before you install
High install friction due to source distribution format. The package is abandoned—last release was 2012-06-22—and no longer maintained. Modern Python versions have built-in json support that supersedes this wrapper's original purpose.
Package targets Python 2.4–3.1 and is not maintained for modern Python versions; compatibility with current Python releases is uncertain.
