Syncline

Syncline is an innovative open-source tool designed for developers, product teams, and analysts who need deep insights into user sessions and backend operations. It uniquely combines session replays with detailed backend traces and SQL query logs, all synchronized onto a single timeline. This integrated view allows users to understand precisely what happens during a user session, from frontend interactions to backend processing, making troubleshooting and performance analysis more intuitive and comprehensive. What sets Syncline apart is its ability to seamlessly overlay multiple layers of data—visual, trace, and query logs—into one interactive scrubber, enabling a holistic view of user behavior and system performance. Its open-source nature makes it accessible for customization and integration into existing workflows, making it a valuable tool for debugging, performance tuning, and user behavior analysis.
