RibbonDiff - Mac-native diff for text, files, and Git history

Hey Product Hunt - I'm Rei, the maker of RibbonDiff. I built RibbonDiff because I wanted a diff tool that stays useful while I'm still editing. A lot of compare tools are good at showing changes, but awkward once you want to keep refining the content. RibbonDiff is a Mac-native diff app with two editable side-by-side panes, live updates, and a visual ribbon that links matching change blocks so larger edits are easier to follow. It works well for code, docs, config files, logs, and AI-assisted edits when you want to verify what changed before moving on. Version 4.0 adds Workspace for reviewing related files together, plus Version History for comparing against Git-backed revisions inside the app. RibbonDiff is free to download, and Pro unlocks file workflows, Workspace, and Version History. I'd especially love feedback on whether the ribbon helps you scan big diffs, whether Workspace and Version History fit your review flow, and what you still miss from your current tool. Thanks for checking it out - I'll be around in the comments.
