Code to Flow
Code to Flow converts source code into visual flowcharts and diagrams, supporting multiple languages and diagram types to make program logic easy to follow.
About
Code to Flow takes code you paste in and produces interactive visual diagrams that map out the logic and structure of that code. It supports languages including Python, JavaScript, Java, C++, Go, and Rust, and can generate flow diagrams, sequence diagrams, class diagrams, and user journey maps. Diagrams can be exported as PNG, SVG, or PDF and edited directly in the interface. The tool is useful for debugging, code reviews, onboarding new contributors, and building technical documentation. A free tier allows a limited number of diagrams per day; unlimited access is available through a monthly subscription or a one-time lifetime purchase.
