How is this calculated?

A 0-100 score computed nightly from four factors: maintained (40%: recent commits and steady activity), popular (25%: GitHub stars, log scale), easy to install (20%: platforms, install notes, setup guides, Docker image) and light to run (15%: minimum RAM, ARM support). Factors without data are left out and the rest are rescaled.

First-install notes

  • Set your ngrok token before starting Before starting the tunnel, put your ngrok authtoken into an environment variable (a hidden setting your program can read) or directly in the code. Without it, ngrok will not open the public tunnel for your app. source
  • Tell ngrok the local port your app uses In the code where you start the tunnel, set addr to the local port (the number your app waits for on your computer), for example 8080 or 3000. If it points to the wrong port, the tunnel can start but visitors get an error because the app is not listening there. source
  • Use the printed ngrok URL to share it After the tunnel starts, copy the public https ngrok.app address shown in the output. That temporary link is how people on the internet can reach the app running on your machine. source

Common questions

Do I need to configure a token before ngrok opens a tunnel?

Yes. Set the ngrok authtoken in an environment variable or directly in the code before starting the tunnel. Without it, ngrok will not open the public tunnel.

Why can a tunnel start successfully but still give visitors an error?

This can happen if the tunnel addr points to the wrong local port. Set it to the port your app actually listens on, such as 8080 or 3000.

Is the ngrok URL that is printed after startup persistent?

No. The public https ngrok.app address shown after the tunnel starts is described as a temporary link for people on the internet to reach the app on your machine.

Can one ngrok account open multiple tunnels at once?

A self-hosted user reported that ngrok only allows a single tunnel per user account.
