No worries! This forum is focused on using Local which is a tool for developing WordPress sites offline.
The reason that it shows up in searches for ngrok tends to be that we used to rely on ngrok for a feature called “Live Links” – which allows you to share a link to the site on your personal machine to anyone across the world, through the internet.
There were limitations to using ngrok, so while we still use it for some things, we are currently building our own site tunnel solution for pro users.
