Ozon Price Tracker
A Chrome extension that turns product-price monitoring into a private, useful history with alerts.
Problem
Shoppers need a simple way to follow product prices over time instead of checking listings manually.
Solution
A Chrome extension that records product prices locally, makes historical changes easy to review, and surfaces alerts when attention is useful.
Architecture
The extension uses a Manifest V3 browser-extension architecture, with a React and TypeScript interface backed by IndexedDB for local price history.
Technical decisions
- Use Manifest V3 for the current Chrome extension platform.
- Store price history in IndexedDB so it remains available locally.
- Support import and export so people can keep control of their history.
- Cover important behavior with automated tests.
Challenges
- Keeping price history useful without making routine tracking feel intrusive.
- Designing data portability alongside local-first storage.
