Comparados is a web application designed to retrieve and compare prices from different stores using web scraping techniques. The project uses Puppeteer for automated data extraction and is intended as a simple, straightforward tool for quickly searching products.

The project architecture keeps the backend and frontend completely decoupled, which facilitates maintenance and scalability. Neither WebSockets nor Express are used, prioritizing a lightweight communication approach focused on on-demand queries.

One of the key aspects of the development was the implementation of a flexible, country-based configuration, allowing the region from which prices are retrieved to be easily changed, ensuring results aligned with each user’s local market.

The project’s approach focused on functionality and clarity, prioritizing a simple search experience while addressing a real problem: accessing price information from multiple stores in a single place.
