Overview

If you're looking to enhance your Rails application with user-focused recommendations, the simple_recommender gem is worth considering. It seamlessly integrates with your existing PostgreSQL database to provide the popular "Users who liked X also liked Y" functionality without the need for additional data storage in Redis. This not only simplifies the setup but also reduces operational complexity, allowing developers to focus on enhancing user experiences rather than managing data redundancy.

The gem is designed for efficiency, using PostgreSQL's powerful integer array operations to deliver real-time recommendations. With impressive performance metrics, it is tailored for applications with fewer than 100,000 records. This offers an appealing option for small to medium-sized projects that want to develop personalized content suggestion capabilities without the hassle of extra data handling tools.

Features
