The ngrok 1.X service has shut down and all users are encouraged to upgrade to ngrok 2.0.
The easiest way to continue using ngrok is to upgrade to 2.0. ngrok 2.0 has been available for nearly a year and it is a faster, more stable and more powerful tool. I hope that you'll love it even more than the original.
Emails with notice about the sunset schedule were sent out, but you may not have gotten one if you did not have an ngrok.com account.
ngrok 1.X is being shut down for a number of reasons including operational burden, technical limitations and most importantly that continuing to support 1.X causes user confusion when developers get started, damaging ngrok's simplicity and ease-of-use.
It's been nearly three years since ngrok first launched and I want to thank all of you who have been there and supported it from the very humble beginnings. What started as a small project has now reached over 75,000 developers all across the world. And it's not stopping there; there are many more exciting changes ahead.
If you have any questions, comments, concerns, or just want to say hi, please don't hesitate to get in touch.
