A high level diffing library for rust based on diffs

Moulti is a CLI-driven Terminal User Interface (TUI) displaying arbitrary outputs inside visual, collapsible blocks called steps.

Go implementation of the Patience Diff algorithm

Applies diffs based on context, not line numbers. Useful for AI-generated code.

Inline file-level git diff overlay for Neovim — see and edit your uncommitted changes in place.

Production-ready C# library for parsing and applying unified diffs — sync/async/streaming APIs, DiffX multi-file format, memory-efficient algorithms, and LLM-generated diff tolerance.

Natural-language code transformation as a Python library: generate_diff turns a plain-English goal into a unified diff, smartapply applies it resiliently. CLI included. Formerly gptdiff.

Next Edit Suggestion (NES) - A conceptual methodology for AI coding assistants that learn from editing patterns and predict the next logical edit using unified diff format and real-time streaming.

A text diffing library for Gleam — Myers diff, Patience diff, unified format, patch, semantic cleanup, and inline highlighting.

Application to colorize unified diffs, with changed word/character highlight.

git apply - style patching, but more forgiving — a Python unified diff applier for AI/chat-generated patches with Markdown fence stripping, context matching, dry-run, and backups.

Browser-based diff viewer: paste or upload patches, view side-by-side or unified diffs with syntax highlighting.

A high level diffing library for go based diffs

A pure local diff viewer - view any git diff command in a phabricator-like diff view. For phabricator, you create a diff with `arc diff main` and view it on phabricator server, with this tool you run `local-arc diff 'git diff head~1'` and view diff in browser with a local server

Lightweight Linux terminal tool for safely applying AI-generated unified diff patches using git apply.

Apply unified diffs and fuzzy search/replace edits in pure Python - the patch engine for code agents. No git, no patch binary.

Apply the sloppy unified diffs LLMs write. A Go port of aider's fuzzy hunk applier, verified against the JavaScript original.
