Vivix – See inside JavaScript as it executes (open source)

Vivix is an open-source developer tool that provides a visual, real-time view of JavaScript execution, allowing developers to see how their code runs step-by-step inside the browser. It is designed for frontend engineers and educators who want to debug complex logic or teach JavaScript concepts more intuitively. The project is interesting because it transforms abstract runtime behavior into an interactive, inspectable diagram, making it easier to understand closures, async flows, and scope chains.
