Netviz

Netviz is a browser-based app for designing network architectures visually.

Add components like servers, proxies, and databases to a canvas, connect them to map data flow, organize them into layers, and customize every detail.

Important

This project was entirely created using AI, but the application has been thoroughly tested.

This project was built primarily for my personal use, so I will not be merging pull requests or adding new features unless I need them myself. If you want to make changes or add features, feel free to fork this repository.
