Detect if the user uses a VPN

Step 1

Strange :thinking: seems like they changed their API or smth…
I found another API: https://proxycheck.io/
You can parse the result with the JSON component, and get the “type”

Here with nordvpn:

I am connected to the belgium server, and you can see that in the “type” return “VPN”

(I’m using ubuntu so yeah)

Without a VPN it will output "type": "Residential"

So from this you can check if the value of “type” is a VPN.

Cool, it works, sometimes. Here’s when I am connected to another server

Their server is probably hosted with Azure

Maybe :thinking:
Well you just have to test if “type” is “Residential” maybe it’ll work better

Please make a Extension

Ssarch the extensions directory for an extension

You may give this a try:
com.django.djvpnchecker.aix (5,4 KB)

Edit: This is no official extension, just a helper extension for you to test if this solves your issue.

Is this the first time you are publishing this extension?
Up to now it is not in the extensions directory…
Could you please start a new thread in category Extensions to publish the extension including a short documenation?

This extension has only one method that throws out a boolean, True or false.
But the question is:
Does it solve your problem or not?
BTW, in times of restriction to 5 extensions for a non Premium user an extension shouldn’t have only 1 method :wink: So I wouldn’t release it.

don’t worry about that…
there are also other builders… and MIT App Inventor does not have any restrictions…

No, you have to use boolean true or false blocks or just remove them completely like this

if DjVpnChecker.IsVpnActive
then close application
else open another screen ...
