Detailed overview

Swimm now provides agentic modernization services rather than a self-serve documentation tool. Offerings include API-first architecture extraction, an agentic context layer that gives AI coding tools (Copilot, Cursor, Claude Code, MCP servers) verified system knowledge, and large-scale migrations such as .NET, Java, monolith-to-microservices, and mainframe modernization. Engagements run through staged phases—Assessment, Specification, Modernization, and Enablement—each fixed-price, delivered via a customer workspace with deterministic code analysis, AI-assisted execution, and expert validation. Swimm supports on-premise/air-gapped deployment and is SOC 2 and ISO 27001 certified, targeting enterprise teams modernizing large or legacy codebases rather than individual developers seeking free documentation tooling.

Pricing details

Custom, fixed price per engagement stage (Assessment, Specification, Modernization, Enablement); no public self-serve or free tier—pricing via contact/quote.
