What is Swimm?

Swimm is a documentation tool designed to help development teams create and maintain accurate code documentation. It works by connecting directly to your codebase, allowing you to document code behaviour, architecture decisions, and workflows in a way that stays linked to the actual code. This approach helps prevent documentation from becoming outdated when code changes. The tool is built for software teams of all sizes who struggle with keeping documentation in sync with their changing codebases. Rather than writing documentation separately, Swimm lets you document code in context, making it easier for new team members to understand systems and for existing developers to maintain institutional knowledge. Swimm operates on a freemium model, meaning you can start documenting for free and upgrade for additional features and team collaboration capabilities.
