jd is a command-line utility and Go library for diffing and patching JSON and YAML values. It supports a native human-readable diff format plus JSON Merge Patch (RFC 7386) and a subset of JSON Patch (RFC 6902), with format translation and a WASM-based web UI.

Use cases

• diff two json files
• apply a json patch to a file
• convert between json patch and merge patch formats
• diff yaml files
• show structural differences between json documents in ci
• treat json arrays as sets when diffing

When to choose

• you need structural, path-aware diffs of JSON or YAML rather than line-based text diffs
• you want to create or apply RFC 6902 / RFC 7386 patches from the command line
• you need a Go library for JSON diffing or patch translation
• you want minimal array diffs with context to keep patches valid

When to avoid

• you need line-based diffs of arbitrary text files - use GNU diff instead
• you need full JSON Patch support including all RFC 6902 operations
• you need to diff formats other than JSON and YAML
