allplaatsplus is a lightweight, privacy-friendly listing cleaner for second-hand marketplace sites. It removes sponsored, promoted and paid storefront listings (the "ads") from search results on Marktplaats (NL), 2ememain (BE/FR), 2dehands (BE), leboncoin.fr (FR) and kleinanzeigen.de (DE) , blocking them at the network layer before they render, plus a DOM fallback for server-rendered pages.

You can also filter by keywords in the title/description, block listings from specific cities/countries, enable a comfortable dark mode, and upgrade thumbnail photos to HD. A badge and popup panel show exactly how many ads and requests were blocked on each page.

Everything runs locally in your browser — it never sends your data anywhere.
