Difftray brings code review to your phone and tablet. Pair it with the open-source Difftray desktop app, then read git diffs, browse every changed file, and leave line-by-line comments — all over your own local network, with no cloud in between. Difftray is a companion app. It works alongside the Difftray desktop app running on your Mac. Scan a QR code once to pair, then pick up any project from the couch, a meeting room, or the other side of the office. REVIEW DIFFS ANYWHERE Read inline diffs with real syntax highlighting, sized for small screens. See additions and deletions at a glance, move between changes, and mark each file reviewed as you go. BROWSE CHANGED FILES Step through every changed file in a project and see exactly what moved, with per-file and total added/removed line counts. HAND OFF TO YOUR CODING AGENT Leave comments on the lines that need work, then export them as an agent-ready prompt. Copy it or share it straight into your AI coding agent so the fixes are queued up before you're back at your keyboard. ALL YOUR PROJECTS Every project open on your desktop is one tap away on your phone or tablet. PAIR LOCALLY, STAY PRIVATE Connect by scanning a QR code or entering a short code — no account, no sign-up. Your phone talks directly to your own computer over local Wi-Fi, or over your private Tailscale network when you're away from your desk. Pairing is end-to-end encrypted, and your code never touches a server we run. REQUIREMENTS Difftray requires the free, open-source Difftray desktop app with its companion server enabled. This mobile app is a companion to that desktop app and does not work on its own. Pair your phone, step away from your desk, and keep reviewing.
