Filtr Nieruchomosci

Filtr Nieruchomosci is a browser extension that helps you organize browsing of property listings on Otodom.pl and OLX.pl.

- Hide listings
You can quickly hide individual ads without logging in and without changing search results on the site. The hidden list is stored locally in your browser.

- Blacklist in the extension popup
You see the total number of hidden ads and a breakdown by city (without splitting by platform). For each city, you can clear only that part of the list or clear the entire blacklist with one button.

- Marking “agency” / non-private listings

Otodom — on the search results list, listings from real estate agencies can be visually highlighted.
OLX — the extension can mark listings from sellers other than private individuals (including links that redirect to Otodom), based on data from the listing page (in the background, with request rate limits).
Convenience on the OLX list
The hide button is next to the price on the listing card. When filtering the OLX list (e.g., companies only), highlights may stay consistent with that filter.

Interface language
In the extension settings, you can choose Polish or English for the popup interface.

Privacy
Data about hidden listings is stored only on your device (local browser storage); the extension does not require an Otodom or OLX account.
