Please take some time to answer the following questions as best you can:

• Why is it awesome?

  NetBird allows to create private meshed networks very easily with a nice UI. It connects peers through Wireguard with configurable policies to enhance security.

• Have you used it? For how long?

I have been using it for almost a year now.

• Is this in a personal or professional setup?

Both. I use it to connect to my home and work networks.

• How many devices/users/services/... do you manage with it?

Around 50 devices.

• Biggest pros/cons compared to other solutions?

Pros: very easy to setup, a lot of admin control through policies, custom dns resolver to connect to peers, very active development, network routing...
Cons: NetBird is still pretty early, and sometimes lack of features

• Any other comments about your use case, things you've found excellent, limitations you've encountered... ?
