Confdiff – semantic diff for config files (JSON/YAML/TOML) that redacts secrets

Confdiff parses JSON, YAML, TOML, INI, .env, Java properties, CSV/TSV, and XML files into a data model and reports only semantic differences—ignoring reordered keys, formatting changes, comments, or quoting variations. The tool can redact secret values, replacing them with stable fingerprints, and supports cross-format, whole-tree, and multi-document comparisons, all executed client-side in the browser.
