How Session Rewind built an affordable session replay tool

Session Rewind is a cost-effective session replay tool developed to challenge the high prices set by market leaders in the industry by leveraging modern cloud technologies. The process involves using Tinybird's real-time analytics platform built on ClickHouse®, along with Kafka for data streaming, to efficiently handle high data throughput and storage needs while minimizing operational costs. By employing AWS services and Tinybird, Session Rewind reduces its DevOps surface area and enhances performance, enabling it to deliver accurate session replays at a steep discount. The tool addresses technical challenges such as high data storage requirements and fast queries on user-defined properties, and it supports a high iteration speed for developing new data transformation prototypes. As the product gains traction, with over 50 companies already using it, the team plans to further reduce costs and introduce new features like heatmaps and funnel analysis, all while maintaining a lean operational approach.
