Swimm

Swimm is an Application Understanding Platform that leverages AI-powered static analysis to reverse engineer legacy code, particularly mainframe applications. It builds a knowledge base from the code, revealing architecture, patterns, and hidden logic, and creates a living inventory of programs, modules, and dependencies with explanatory names. This allows organizations to inventory, assess, and understand their systems, uncover buried business logic, and identify areas for change. The platform helps teams plan migrations, write specifications, and align around modern architecture. It provides a complete overview of a codebase's architecture, documents business logic, and automatically generates diagrams with explanations of dependencies, user screens, variables, and job flows. Swimm is designed for CIOs to accelerate timelines and de-risk initiatives, for product and analysts to create specs without relying on mainframe experts, and for developers to understand code connections. It emphasizes accurate, hallucination-free explanations through a combination of deterministic code analysis and AI, and is enterprise-grade, secure (SOC2, ISO 27001), scalable, and customizable, supporting various deployment models including on-premise and cloud.
