The ease of use is one thing I love about this product, it's almost like magic! It allows me to have 2 servers in my same network connected with each other which was impossible when using VPNs or even having multiple computers open at once for testing purposes. There are some bugs here and there but nothing that would stop you from getting down to business. If your looking for an easy way to get over firewalls then this service can do just that without any issues. We were solving our problem of being able to connect two dev environments together while still allowing them access through their respective firewall rules. The best thing about this is that it works with my existing VSCode extension, so I don't have any problems setting up new extensions for different services. There are no downsides in using this as well. It's free! If you're looking for something simple but effective then definitely go for it. We use ngrok for our backend APIs (built with NodeJS) which helps us test them without having to worry about network issues.
