SuperFLOW

SQL flow and lineage visualizer for web-based SQL editors. Best experienced in Superset SQL Lab.

SuperFLOW helps you understand complex SQL through flow. It visualizes SQL structure as logical graphs for sources, CTEs, joins, filters, subqueries, outputs, write targets, and column lineage. You can inspect multi-statement worksheets in Script View, trace upstream and downstream dependencies, and move between SQL text and graph focus. SuperFLOW works best in Apache Superset SQL Lab, where it supports deeper integration such as bidirectional focus, selection-follow, and SQL Lab layout controls. Other web-based SQL editors are supported on a best-effort, read-first basis. If direct page access is limited, you can still analyze SQL with Clipboard or Paste SQL mode. SuperFLOW is designed around the current tab. Enable a site once, and keep using SuperFLOW there without granting blanket always-on access everywhere.
