A Scalable Architecture for Real-Time Multi-Vendor Price Aggregation and Comparison

Nowadays, Quick Commerce (Q-Commerce) has rapidly transformed retail business by enabling ultra-fast delivery of essentials through platforms like Blinkit, Zepto, Swiggy Instamart, and BigBasket. However, inconsistent pricing and also lack of transparency across platforms creates confusion for customers while making decisions on purchasing. This paper addresses this challenge by designing and implementing a scalable centralized architecture that will aggregates and compares real-time product prices from multiple vendors or platforms. Also, the proposed architecture allows customers to view delivery times, offers, and vendor reliability. Finally, the proposed architecture enables customers to effortlessly find the best value, save money, and make better purchasing choices, while simultaneously driving healthier competition in the market.
