Applies JSON Patches according to RFC 6902, enabling programmatic modification of JSON documents through a standardized patch format.

Low friction installation with a single pure-Python runtime dependency (jsonpointer). Actively maintained with recent commits and stable production status since 2011.

Modified BSD License (permissive) allows commercial and private use with minimal restrictions, requiring only license and copyright notice retention.

Usage

pip install jsonpatch
import jsonpatch
patch = jsonpatch.JsonPatch([{"op": "add", "path": "/foo", "value": "bar"}])
result = patch.apply({"baz": "qux"})

Verdict: Mature, well-maintained RFC 6902 implementation with no known vulnerabilities, permissive licensing, and minimal dependencies. Suitable for production use in JSON document manipulation workflows.

Needs verification
