snapwatch

Watch what an AI agent does to your project — live, as diffs, without touching your git repo.

`snapwatch` points at a directory, snapshots it into a **shadow git repository** every time something changes, and shows the resulting diffs in your browser as they happen. Built for one job: sitting next to Claude Code, Codex, Aider, Cursor or any other agent and seeing exactly what it just did — file by file, line by line, in real time, even in projects that aren't under version control.

The project's own `.git` is read for the history sidebar, never written to, and not required at all.

• Live feed — every save becomes a snapshot; snapshots stream into the page over SSE as side-by-side, syntax-highlighted diffs under a sticky timestamp. Infinite scroll back through the whole session.
• Debounced, not spammy — a burst of writes (an agent editing 12 files, a formatter running) becomes one snapshot, not twelve.
• Git-aware — if the project is a git repo, its commits show up in the feed as ● sha subject markers and branch switches as ⎇ switched to …. The file churn caused by a checkout is folded away instead of shown as "changes".
