Swimm Logo
Swimm
Automates reverse engineering of complex, legacy codebases to produce accurate, living documentation, architecture maps, and business-rule specifications that accelerate modernization.

Swimm extracts and documents the structure and logic of large, aging codebases—especially mainframe and legacy systems—by building a living inventory of programs, modules, screens, jobs, and dependencies with explanatory names.

The platform combines deterministic static analysis with AI-generated explanations to create readable specs, diagrams, and traceable business rules that non‑technical stakeholders can use. It integrates with developer tools such as GitHub, VS Code, and JetBrains to keep documentation synchronized with code.

Designed for enterprise adoption, Swimm supports cloud and on‑prem deployments, compliance standards (SOC2, ISO 27001), and scalable processing for very large codebases, enabling teams to reduce discovery work, de-risk migrations, and speed modernization initiatives.
