Limits in ngrok's free plan
Below are the limits enforced in the ngrok free plan. For more details on increasing or removing these limits, refer to the ngrok paid plans.
TCP Endpoints
In an effort to reduce abuse on the ngrok platform, we now require a valid payment method be added to your account before you can start TCP endpoints. This card will not be charged as long as you remain on the free plan.
Endpoints
As a free user of ngrok you can define up to 3 endpoints in a configuration served by the same agent at the same time.
What is an endpoint?
An endpoint is any device, app, or API that connects to a computer network. When you put an app online at foo.ngrok-free.app (using your free static domain), that’s one endpoint. If you connect to a device using a TCP protocol at 9.67. 1.100, that’s another endpoint.
