Welcome to the Experiment!
This tool was built as part of my personal "vibecoding" learning map. I wanted to create a straightforward way for fellow Network Engineers and IT Administrators to visualize traffic flows, whether for your own internal networks or for your customers' environments. I'm excited to share it with the community for you to try out!
A Quick Heads-Up Before You Dive In
This site is an experimental self-effort. While I've put a lot of work into it, it's not a polished enterprise product. It isn't perfect, and you might encounter a few glitches, missing features, or conceptual similarities to other apps on the market.
This tool is provided strictly for educational, planning, and visualization purposes. By using it, you agree that it is provided "as is" without any warranties. I assume no liability for any network disruptions, design flaws, data inaccuracies, or operational issues that might result from using these charts. Always verify your final designs and flows!
I highly value your input. If you hit a bug, have an idea for a new feature, or see a way to make it better, please share your feedback. Let's improve it together!
