Diff Anything - 2026 Pricing, Features, Reviews & Alternatives

Diff Anything is a private, local-first desktop comparison and merge application available on macOS 13 Ventura or later and Windows 10 or later. It supports a broad range of file types including source code, spreadsheets, CSVs, JSON, XML, YAML, PDFs, images, and binary files, making it applicable across engineering, data, finance, and operations workflows. All processing occurs on-device with no data transmitted to external servers, which suits teams operating under strict data governance or compliance requirements.

Diff Anything provides side-by-side and inline diff views with syntax highlighting, structured diffing for data formats, and merge conflict resolution tools. File comparison can be triggered directly from the command line or integrated into version control workflows. The interface surfaces granular change details at the cell, line, or node level depending on file type, reducing the manual effort required to audit changes across complex documents or codebases.

For teams handling sensitive data or working in air-gapped environments, Diff Anything delivers a capable alternative to cloud-dependent comparison tools. Its broad format coverage and offline-first architecture allow consistent use across varied file types without requiring multiple specialized utilities or network connectivity.
