About TOML Compare
Compare TOML as structured data
The comparer parses TOML before diffing, so tables, inline tables, arrays, and scalar values are compared by their data structure. This is more useful than a raw text diff when table order or formatting changes.
Useful for project config reviews
Use it to review Cargo.toml, pyproject.toml, and other TOML configuration changes. Sorting keys can reduce noise, while the side-by-side view keeps the original and changed file easy to compare.
Browser-only diffing
Parsing and comparison run locally in JavaScript. That keeps dependency versions, credentials, or environment-specific settings from being uploaded while you inspect the diff.
