Free Chrome extension for flat hunting in Prague

Find the same flat cheaper – without opening ten tabs.

While you look at a listing on Sreality, Bezrealitky or iDNES, a small cat box in the corner shows the most similar flats from other Czech real estate sites – with price, size, photo and a direct link.

How it works

Install once, then just browse flats the way you already do.

  1. 1

    Open a flat in Prague

    Any flat for rent or sale on Sreality, Bezrealitky, iDNES and other supported sites.

  2. 2

    The cat box appears

    After a few seconds it shows up in the bottom-right corner with the most similar flats it found.

  3. 3

    Compare and click

    Click a flat to open it on its own site. Click the cat icon in Chrome's toolbar to change your filters.

Everything you need to compare, in one small box

  • The 3 most similar flats, right away

    Same layout (e.g. 2+kk), same neighbourhood or district, similar size and price. Scroll or click “Show more” for the rest.

  • Price difference at a glance

    Blue means cheaper than the listing you're viewing, red means more expensive.

  • One flat, many sites – shown once

    Agencies often post the same flat in many places. You see where else it's listed – and if one has no agency commission, you can save a month's rent or more.

  • “No commission” and “furnished” badges

    Plus monthly fees wherever the listing shows them.

  • Your own filters

    Set a rent range, a purchase price range, or show furnished flats only.

  • Don't speak Czech? No problem

    Works with Chrome's page translation, so it's easy to use even if you're new to the city.

Private by design

Reality Scanner CZ runs entirely in your own browser.

  • Free, no account, no tracking

    No sign-up, no ads, no analytics inside the extension.

  • Your data stays with you

    It reads other sites' search results only when you open a listing, and never sends your data anywhere.

  • Only your filters are stored

    The only thing it saves is your filter settings.

  • Listings stay where they are

    Listings and photos stay on their original sites – the extension only links to them.

Frequently asked questions

Is it really free?

Yes. Reality Scanner CZ is free, with no account and no ads.

Does it work outside Prague?

Not yet. It currently covers Prague only, and standard flat layouts from 1+kk to 6+1.

I don't see the cat box. What should I do?

It appears only on flat listings in Prague, a few seconds after the page loads. If you just installed or updated the extension, refresh the page.

Which browsers are supported?

It's built for Google Chrome on desktop. Other Chromium-based browsers that install extensions from the Chrome Web Store usually work too.

Is it connected to Sreality, Bezrealitky or other sites?

No. Reality Scanner CZ is an independent project and is not affiliated with any real estate website.

Your next flat might already be cheaper somewhere else.
