Swimm

Swimm is a code modernization and codebase understanding company that combines static analysis, generative AI and senior engineers. It describes itself as a product enabled service company, so much of what it sells is delivered as scoped engagements rather than self serve software. The offering has three parts. API first architecture extracts embedded business logic from frontend and backend code into reusable services. An agentic context layer builds a validated, MCP queryable knowledge base so that tools such as Copilot, Cursor, Claude Code and internal agents understand a codebase. Large scale migrations cover .NET migration, Java migration and monolith to microservices work. Each engagement begins with an assessment that fixes scope, risks and success criteria. Swimm's engine performs deterministic analysis to map dependencies, entry points, data flows, dead code and cross repository relationships. AI agents then apply verified patterns across the code, and subject matter experts validate the output. Customers follow progress in a live workspace that shows repositories, the work plan, findings, tests and deliverables. The pricing page focuses on mainframe and COBOL understanding with auto generated documentation and flow visualization. Pricing is not listed as a price table. The site states that pricing is based on the number of lines of code to be understood, offers flexible project pricing for system integrators, and offers proof of concept trials on request. It supports on premises, cloud and air gapped deployments, uses a customer's own LLM instance such as Azure OpenAI Service, and states SOC 2 and ISO 27001 compliance.
