Around Innsbruck

10–13 Jan · usually −8 to 4 °C, some rain

A real video. Outside built it on 14 November 2026 for a stay in Innsbruck, 10 to 13 January. The photos on this page are from Wikimedia Commons; the extension finds its own, live.

How it works

A listing shows you the room. Outside shows you the rest.

  1. 01

    Open a listing

    A small badge appears on the photos of any Airbnb or Booking.com listing. It tells you what it is doing while it works.

  2. 02

    It reads the live web

    Places, opening hours, tours with today's prices, concerts, the weather. Fetched at that moment, for the dates in the listing's address.

  3. 03

    Watch for half a minute

    A narrated video of under thirty seconds. Every number the voice says is checked against the source it came from.

Built from Google Maps / Viator / GetYourGuide / Songkick / Open-Meteo / Wikimedia Commons, fetched through Context.dev

Your dates

It knows when you're going.

Outside looks up what the weather is usually like on your dates, from the same days in past years, and searches for what people do then. Each thing to do comes with its rating, the drive, and an offer you can book.

Install

Six steps, about two minutes.

Outside is not in the Chrome Web Store yet, so Chrome loads it from a folder on your computer. For that it needs Developer mode switched on.

  1. Download the extension

    One small zip file.

    outside-extension.zip
  2. Unzip it

    On a Mac, double-click the file. On Windows, right-click it and choose Extract All. You get a folder called outside-extension. Put it somewhere it can stay: Chrome runs the extension from that folder, so do not delete it.

  3. Open Chrome's extensions page

    Type the address below into Chrome's address bar and press Enter. Web pages are not allowed to link there, so copy it.

    chrome://extensions
  4. Turn on Developer mode

    The switch is in the top right corner of the Extensions page. Three buttons appear on the left once it is on.

  5. Load the folder

    Click Load unpacked and choose the outside-extension folder: the one that has manifest.json directly inside it. On Windows that can be a folder of the same name inside the first. Outside appears in the list.

  6. Open a listing

    Go to any place to stay on Airbnb or Booking.com and look at its photos. The badge builds the video, then turns into a play button. To choose your interests, click the puzzle icon in Chrome's toolbar and pin Outside.

Questions

Before you install.

Why does Chrome need Developer mode?

Extensions normally come from the Chrome Web Store. Outside was built at the Junction 2026 hackathon and is not listed there yet, so Chrome has to load it from a folder, which it only does in Developer mode. Leave the switch on while you use Outside.

What does it read, and where does it go?

Only the listing page you have open on Airbnb or Booking.com: its address, title, location, dates, currency and the links to its photos. That, with your chosen interests, is sent to the Outside server, which builds the video. There is no account, and the extension does not read any other page.

Which pages does it work on?

Full listing pages on Booking.com and on Airbnb's sites in 29 countries. It does nothing on search results, maps or the home page.

How fresh is the information?

Each video is built from pages fetched at that moment and is kept for six hours, then rebuilt. The last scene names every source and says when the data was read. Drive times are estimates and are marked with ≈. Prices are the "from" prices the marketplaces showed.

The badge says "Server not running". What now?

The extension could not reach the Outside server. Press Retry. If many people are trying it at once a video can also take longer than usual, because the live sources are fetched at a limited rate.

How do I update or remove it?

To update, download the zip again, replace the folder, and press the reload arrow on Outside's card at chrome://extensions. To remove it, press Remove on the same card and delete the folder.

Go on, step outside.
