┤ HERO ├git diff → diffing

LOCAL-FIRST · NO ACCOUNT · NO CLOUD · MIT

git diff, reimagined as a review workspace.

diffing is a local-first CLI that opens your changes in a GitHub-like web UI or a native TUI — comment, hand off to your AI agent, and review plans before any code is written. Everything stays on loopback.

TTY opens the preferred interactive UI (web by default). Pipe/redirect prints a unified patch like git diff.
