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.

  • 100% Offline Operation

    The desktop app works entirely offline. Your code never touches our servers.

  • Local Data Storage

    All analysis data is stored locally in SQLite. Delete anytime.

  • SOC 2 Compliant

    Our license server meets SOC 2 Type II compliance requirements.
