What is DiffDeck?

DiffDeck is a TypeScript CLI tool that pipes any `git diff` output—including git commit diffs, git diffs between branches, or git show diffs between commits—into a local browser UI for better git diffs. Run `diffdeck` (or alias it as `gd`) like `git diff --cached`, and it spins up a responsive web app with a file tree, totals like git diffstat, and inline commenting on changed lines. Copy all comments with surrounding context to paste into an AI agent; git binary diffs are not supported but get placeholders.

Why is it gaining traction?

It turns unreadable terminal diffs into a polished, virtualized viewer that handles 20k+ line monsters without freezing, plus merge conflict rendering and persistent comments. The killer hook is one-click export of review notes with code context for agents—perfect for AI-driven workflows where you add feedback then let Claude or Cursor fix it. No GitHub login or repo setup; it's fully local and drop-in.

Who should use this?

Remote devs SSHed into servers needing git show diff for commit reviews without a full IDE. Teams doing git diffs between branches on massive repos like lockfiles or generated code. Anyone pairing with AI agents who wants structured git show diffs feedback instead of screenshots.

Verdict

Try it if terminal diffs pain you and you use AI coding tools—install via npm, alias, done. With 12 stars and 1.0% credibility, it's early (solid README, no tests visible), but mature enough for daily use on non-binary changes.
