# Browser Screening Page

> Free Pinggy tunnels show a one-time browser screening page. It only affects browsers - curl, API clients, and custom User-Agents pass straight through, or send the X-Pinggy-No-Screen header to skip it.

# Browser Screening Page for Free Tunnels

When you open a **free** Pinggy tunnel URL (a `*.run.pinggy-free.link` address) in a web browser, Pinggy shows a one-time screening page before the site loads. 

> **Note that for Pro tunnels, no screening page is shown**.

The page tells the visitor the site is served through a Pinggy tunnel and asks them to confirm before continuing. It is shown for security reasons, so anyone who follows a shared link knows the traffic is proxied and can decide whether to trust it. A visitor sees it only once per browser.

## It only affects browsers

The screening page is served only to browsers. Requests from `curl`, `wget`, HTTP client libraries, webhook senders, and other non-browser tools are never screened - they reach your local service directly. If you are using a free tunnel for an API, a webhook receiver, or any programmatic client, there is nothing to do:

```bash
# Reaches your service directly, no screening page
curl https://abcd-12-34-56-78.run.pinggy-free.link/api/health
```

## Bypassing it for browser-like clients

If your client does send a browser `User-Agent` but you still want to skip the page, use either of these.

### Send the X-Pinggy-No-Screen header

Set the `X-Pinggy-No-Screen` request header to any value:

```bash
curl -H "X-Pinggy-No-Screen: 1" https://abcd-12-34-56-78.run.pinggy-free.link/
```

### Use a custom User-Agent

Any custom or non-standard `User-Agent` skips the screening page:

```bash
curl -A "my-app/1.0" https://abcd-12-34-56-78.run.pinggy-free.link/
```

## Removing it entirely

The screening page applies to free tunnels only. [Pinggy Pro](/#prices) tunnels serve your site without it.
