Swimm is an application understanding platform designed to help organizations analyze and document software behavior. The platform uses deterministic code analysis to extract business rules and decision paths that are traceable to the source code.
The tool is built for enterprise architects, business analysts, and teams managing application modernization. It supports legacy languages, including COBOL, JCL, and PL/I, as well as modern languages, and is designed to analyze over 100 million lines of code.
Key capabilities include mapping codebases to business functions and generating screens to assess legacy user interfaces without running the system. The platform also provides structured context for AI agents through the Swimm MCP.
Buyers should confirm if the platform's focus on large-scale enterprise legacy modernization aligns with their project scale.

Swimm is an application understanding platform that extracts business rules and decision paths from code using deterministic analysis to help teams understand software behavior.
Yes, Swimm supports COBOL, JCL, and PL/I, as well as modern programming languages.
Swimm uses deterministic analysis, meaning the extracted insights and business rules are traceable and verifiable in the source code rather than being inferred summaries.
Swimm is designed for enterprise companies and teams managing large-scale modernization projects, often involving millions of lines of code.
