About Swimm

Swimm is a commercial product that was built around code documentation that stays connected to the source code it explains, so that docs can be updated when the code changes. Its listing in this directory describes it in that role, as a tool for developer documentation.

The vendor's current website, however, presents a broader offering aimed at code modernization. It describes agentic modernization delivered by a team that combines static analysis, generative AI and senior engineers, with services for API-first architecture, a development context layer for AI agents, .NET and Java migration, monolith-to-microservices work and mainframe modernization. Solutions are framed around AI-ready codebases, legacy modernization risk, compliance and audit readiness, and technical due diligence for acquisitions.

Swimm is sold through sales calls rather than self-serve sign-up, and each engagement starts with an assessment of scope, risks and success criteria. Readers should check the vendor's site to see whether the documentation product or the services offering fits their need.
