In this post from 2011 I was explaining that my preferred online tool to draw network diagrams is Since then developed really good and added constantly new features. Unfortunately with the new great additions some not so nice restrictions appeared for the free account.
Those restrictions (like 5 active documents) really make it difficult for me to work with this tool as I got used to a different style.

I’m not a cheap guy! If I would use this tool professionally there would be no problem to buy a subscription package, but at work Visio is saint (unfortunately) and the rest of the time, especially when I’m on my Mac, I just need a fast tool to draw brief network diagrams like for my blog or fast explanation to somebody online. is my recommendation if you rely on online tool to work with Visio documents. Last time when I checked their Visio import tool was doing a great job.

Back to this story, I was looking online for another tool when I came across doesn’t need an account creation, rather it just give you direct access to the tool.
Since you don’t have an account you cannot save your work on the application, but it does offer you the option to save on Dropbox, Google Drive or OneDrive online or directly on your machine.
Later you can open your document from any of these locations.

In terms of shape the tool is pretty generous and the Cisco ones, really important for me, are there:

The tool is very easy to use, it gives you a Visio feeling (if you’re used with this Microsoft software) and works pretty fast for me.

I tried to open a Visio document from my machine…did not work that well:

Importing the same document did not work better:

It seems that in both cases the Riverbed Steelhead shapes loaded fine, but not the Cisco ones.

Well, I would like to see this working, but in the end nothing to complain. I explained already that I don’t need the online tool to work with Visio. It’s nice if it can, but not mandatory for me. I’ll try some more tests with different Visio files, who knows maybe it’s something wrong with my test file.

One feature which I would like to see is the ability to add your own shapes. Who knows maybe in the future.

If you know a better alternative to that has a free option and you consider it better than please let me know.
