Syncline replays a user session as video and the backend distributed trace and the SQL queries that ran - on one synchronized scrubber.
Syncline provides a unified timeline that integrates user session video playback with backend distributed traces and SQL queries. It is an open-source tool designed for analytics and developer workflows, enhancing debugging and performance monitoring.
A source that found nothing is a measurement. A source that has not run is a gap. Neither means the launch lacks the thing.
