Everything You Need for COBOL Analysis
Powerful features designed for enterprise legacy systems.
Dependency Visualization
Interactive graph view of all program calls, file access, and copybook usage across your entire COBOL codebase.
Impact Analysis
Trace all components affected by changes and understand downstream effects before you make modifications.
Data Lineage Tracing
Follow data flow through programs, variables, and files across your codebase to understand data dependencies.
Dead Code Detection
Identify unused programs, paragraphs, and variables to reduce technical debt and simplify maintenance.
Multi-Project Support
Analyze multiple COBOL applications simultaneously with comprehensive project management capabilities.
Built-in Queries
Pre-configured analysis patterns for common tasks like coupling detection and orphan identification.
Custom SQL Queries
SQL-based query interface for advanced analysis and custom reporting on your codebase.
Export Capabilities
Export graph data and query results in JSON, CSV, PNG, SVG, DOT, and PDF formats.
GitHub Integration
Load COBOL projects directly from GitHub repositories for instant cloud-based analysis.
Coupling Detection
Identify hidden dependencies through shared file access and resources between programs.
Call Hierarchy
Visualize complete program call hierarchies and execution flows from any entry point.
File Access Analysis
Track which programs read and write to specific files to understand data ownership.
And Much More
Additional capabilities to streamline your analysis workflow.
Multiple View Modes
Switch between graph, table, and tree views to see your data the way you need it.
Advanced Filtering
Filter by program type, date, call depth, or custom patterns to focus on what matters.
Copybook Management
Track copybook usage, identify orphaned copybooks, find duplicates, and understand data structure inheritance.
Metadata Extraction
Automatically extract author, date, and description from program headers.
Offline Operation
Works completely offline. Your source code never leaves your secure environment.
Enterprise Security
SOC 2 compliant with local-first architecture. Your code stays on your machines.
Export Anywhere
Share your analysis with stakeholders in the format they need.
Enterprise-Grade Security
We understand that COBOL codebases contain sensitive business logic. That's why COBOL Graph is designed with security as a first principle.
