About Swimm
Swimm is known for living documentation that stays in step with a codebase. Its current site focuses on services that modernize legacy systems so that teams can use coding agents on them.
What it does
Swimm offers services that help teams update older software. The work starts with a verified map of the existing system, covering its rules, flows and dependencies, traced back to the source code. On top of that map, the team builds or updates the application and prepares the codebase so coding agents can work in it with verified context and guardrails. Each of the three services can be used on its own or together with the others.
Key features
- Verified map of rules, flows and dependencies
- New application built module by module
- Tests that confirm each business rule carried over
- AI Operability score for the codebase
- Context and guardrails for coding agents
Who it's for
Engineering leaders and IT managers who have older systems that slow down releases. It also suits teams that want to add new features with AI coding tools but find the existing code hard to work with.
Pricing and good to know
Work starts with a scoping call booked through the site. Because the services are delivered by the vendor's team, much of the process depends on their experts, so plan for that involvement from the start.
