Show HN: Git-Watchtower – Quickly Manage 5 plus Claude Code on the Web Threads

I've been using Claude Code on the web a lot, often running multiple sessions on different branches at the same time. The problem is there's no easy way to know when a branch has been updated or what changed - you end up tab-hopping between GitHub and your terminal trying to keep track of everything. So I built Git Watchtower - a terminal UI that polls your remote and gives you live updates when any branch gets new commits. When something changes you get a visual flash + optional audio notification, can preview the diff, and switch to that branch with a single keypress. It auto-pulls your current branch too, so you're always looking at the latest code. What it does: - Monitors your remote for new commits, new branches, and deletions - Visual + audio notifications when updates arrive - Preview commits and changed files before switching - Auto-pull when your current branch is updated - Activity sparklines showing 7-day commit history per branch - Optional built-in dev server (static or custom command like next dev) that restarts on branch switch
