Browser Monster Index · Open data
How websites track you, in numbers
Every check people run on Browser Monster adds to this public dataset. We open each homepage three times from London (doing nothing, clicking reject, clicking accept) and record what loads, so you see what a visitor in the UK sees. Banners and trackers can differ in other countries.
