Overview
Capture Whatnot auction sales with frequent polling and tab screenshots for audit trails.
Update 2/27/26: Added profit calculation when running on your own stream if you have "Cost Per Item" filled out on the items you're selling. Update 1/10/26: Fixed app to work with Whatnot's new requirement for the user to be logged in to fetch sold item data. Whatnot Double Check by Resellbot Overview: Chrome extension that records Whatnot livestream sales with timestamps and screenshots. Built for sellers who want a reliable way to double check who bought what item while selling rapidly. Key Features: One‑click tracking: compact bubble on the stream with a toggle and last‑sale preview. Auto‑track sellers: enter usernames once; tracking starts automatically on their streams. Live Connections: see active streams, status, size, and jump to screenshots. Recorded Streams: browse shows, preview captures, and manage storage. Exports: download all screenshots as a ZIP and show data as JSON. Storage insights: per‑stream size plus overall usage vs. browser quota. How It Works: Detects sales from the stream’s Whatnot data and captures a frame for each sale. Uses video frames when available, with tab screenshot fallback as needed. Runs locally in your browser (IndexedDB); no cloud uploads or external storage. Why It’s Useful: Clear audit trail for customer support, claims, and record‑keeping. Quick asset creation for social, listings, or post‑show recaps. JSON export for bookkeeping, analytics, or custom workflows. Tips for Best Results Put the livestream in its own window and keep it visible for consistent captures. Use auto‑track for frequent sellers so recording starts hands‑free. Periodically export older streams to keep local storage lean. Compatibility: Google Chrome (Manifest V3). Designed to sit neatly above Whatnot Spy; both can be used together.
