Chrome Extension Price Tracker

An e-commerce analytics startup needed a Chrome extension that could monitor prices across 10,000+ products on major marketplaces, alert users to drops, and display historical pricing charts.

Existing price tracking tools required users to visit a separate website. They wanted an in-browser experience that showed price history inline on product pages and sent instant notifications for price drops matching user-defined rules.

We built a Chrome extension with background price monitoring, in-page price history charts injected directly into marketplace product pages, customizable alert rules, and a dashboard for managing tracked items. The extension now serves 15K+ active users with 99.5% uptime.
