Deal Ninja

Overview

A Chrome extension that does one thing well - it scans Shopify stores for hidden discount codes and surfaces them in a clean sidebar panel. Users can sync their finds to Google Sheets for tracking, and there's a community feature where deals get shared between users. Built with Manifest V3, no frameworks, just vanilla JS keeping it lean. The backend is a Rust API handling the heavy lifting. Has a subscription model via ExtPay for premium features like batch scanning and deal history.
