All diff tools
- difftasticDiffs code by syntax tree rather than lines, so formatting noise and indentation changes drop out. Caveat: it only diffs code, not all diffs.23recommend
- Weave merge toolAn entity-level merge driver that plugs into git and avoids many false conflicts by understanding code structure. Critics report silent corruption and merges that fail on some code.20recommend
- MergirafSyntax-aware Git merge driver that automatically resolves many conflicts and saves rebase time; it fails when both sides insert at the same tree position.19recommend
- semShows which functions and classes changed rather than lines, layered on Git with no repo migration. Critics say it would be rough on something like the Linux kernel.19recommend
- MeldFree visual tool for merging files and comparing folders, recommended for working through tricky merge conflicts.12recommend

- DeffFree terminal app for side-by-side git diff review, with file skipping, extra context and comments to send changes back. Critics say its UI takes too much terminal space.8recommend
- OmniDiffPeople recommend it as a fast, content-aware Git diff tool that highlights only changed characters and produces minimal diffs. Critics mainly object to its AGPL-plus-donation license model.8recommend

- DiffcheckerPeople recommend it for private, browser-based comparison of text and files, with merge support and real-time diffing. The most common caveat is file-size limits.5recommend
- vimdiffPeople recommend vimdiff for reviewing code changes side-by-side in the terminal. The most common caveat is that it is harder to navigate and misses some context.5recommend
