Ngrok (Windows Setup)

1. Create Ngrok Account

  1. Go to the Ngrok website: https://ngrok.com/
  2. Sign up or log in (Gmail login is faster and simpler).
  3. After login, open the Dashboard.

2. Download Ngrok for Windows

  1. Navigate to the official download page from the dashboard.
  2. Download Windows (64-bit) version.
  3. You will receive a ZIP file (e.g., ngrok-v3-stable-windows-amd64.zip).

3. Extract Ngrok

  1. Right-click the ZIP file → Extract All.

  2. Move ngrok.exe to a permanent location, for example:

    C:\ngrok\ngrok.exe

Avoid keeping it inside the Downloads folder.

4. Authenticate Ngrok (One-Time Setup)

Ngrok requires authentication to work reliably.

  1. Open Command Prompt.

  2. Navigate to the ngrok folder:

    cd C:\ngrok

  3. Add your auth token (available in Ngrok Dashboard):

    ngrok config add-authtoken <yourtoken>

If this step is skipped, tunnels may fail or disconnect unexpectedly.

5. Verify Installation

Check if ngrok is installed correctly:

ngrok version

If the command is not recognized, the PATH is not set correctly.

6. Commands

Forward Local Server

Expose a local application running on port 80:

ngrok http 80

Example output will include a public URL like:

https://xxxx-xx.ngrok-free.app

Using Static (Permanent) Domain

If you have configured a static domain in the Ngrok dashboard:

ngrok http --domain=<your-static-domain> 80

Static domains are available only on paid plans.
