How can I see how my account stacks up against my limits?

The ngrok usage page at dashboard.ngrok.com/usage

How often do limits refresh?

Your count of resources against a limit refreshes on the first day of each month.

How does ngrok calculate endpoints for limits?

ngrok uses a combination of unique host:port combinations to calculate endpoints. You cannot have one of more than one of these in use at a time. Unlike other limits, this limit does not refresh at the end of each calendar month, you must simply stop using one endpoint in order to get another.

Need to Increase your ngrok limits?

Request adjustments to limits that conflict with your project by contacting ngrok. To request an increase to a limit, complete the Limit Increase Request Form and we will reach out with next steps.

Why is there an interstitial in front of my HTML content?

ngrok is committed to combating internet abuse. One common abuse of tools like ngrok is the hosting of phishing pages to steal user credentials. To counteract phishing on the platform, we inject an interstitial page in front of all HTML browser traffic on the free tier. Once a user agrees to the page, we set a cookie valid for 7 days for that domain.

If the interstitial interferes with your project, you can bypass it in a few ways.

• From the client accessing the ngrok endpoint, add a header value of ngrok-skip-browser-warning and set it to any value. These requests will bypass the interstitial.
• Change your user agent by setting the User-Agent header to something non-standard, such as MyApp/0.0.1, to bypass the warning.
• Upgrading to any of our paid plans will also bypass the warning.

Code Examples

Axios

axios.get(url, { 'headers': { 'ngrok-skip-browser-warning': '1' } })
  .then((response => {
    console.log(response.data);
  })
  .catch((error) => {
    console.log(error);
  });

Fetch

const response = await fetch(URL, {
  headers: {
    "ngrok-skip-browser-warning": "1",
  },
  // ...
});

SuperAgent

 request
       .get('/endpoint')
       .set('ngrok-skip-browser-warning', '1')
       .then(callback);

JQuery

 request
       .get('/endpoint')
       .set('ngrok-skip-browser-warning', '1')
       .then(callback);

If you are a developer trying to access your own endpoint, you can use a browser extension to customize your browser's user agent value. Here is an example for Chrome.
