[cdpfleet](https://cdpfleet.com/) / [Functions](https://cdpfleet.com/functions) / Live tab Free tool · Live tab # Open a *remote browser tab*. A real browser tab on the cdpfleet fleet, in the country you pick, that you use from this page with your mouse or finger — see a site as visitors elsewhere see it, without a VPN. Free for 3 minutes, no sign-up. [Run it](#try)[API docs](https://cdpfleet.com/docs/functions/livetab) ## Try it Check what a site shows in another country, test a page without exposing your own IP, or try cdpfleet's browsers by hand. With an API key the tab stays open longer, can be shared with someone by link, and hands its cookies back to your code. ## The same from code `POST /v1/functions/livetab` with your API key returns `application/json` — more options than here, such as your own proxy or a browser of your choice.
