📁

Data Sources

Open a .dacpac or import from a database connection. Choose schemas to load their object dependencies.

🔍

Search & Navigate

Find any object instantly with autocomplete. Minimap and schema color coding keep you oriented on large graphs.

🔌

Trace & Find Path

Follow dependencies upstream or downstream. Find the shortest path between any two nodes.

📊

Detect Graph Patterns

Spot islands, orphans, hubs, and cycles at a glance. Explore the loaded dependency structure before making changes.

📄

DDL & SQL Search

Double-click an object to inspect available columns and SQL. Search SQL bodies across procedures, views, and functions.

📈

Schema View

Group large graphs by schema, then expand selected schemas to inspect their objects.

📦
