Free & open-source WordPress plugin
Estatequay takes listings from estate agents’ software and from private owners, checks every ad against German and Spanish law, and lets your editors approve before anything goes live. AI assistants can read it too.
How it works
One path for every listing, with a person in the loop where it matters.
Agents’ software sends OpenImmo or Kyero files to an SFTP inbox, or you enter a feed URL. Private owners send details and photos; your editors enter them.
Area, energy certificate, Spanish licence numbers, a guard against mass withdrawal. A listing that breaks a rule is held, and the reason is named.
New listings of an agent wait for your editors. Approve, or refuse with a reason the provider receives. Every decision is logged.
A fast, reduced listing page with photos, the notes the law requires, a relay contact form and schema.org data.
Withdrawn listings go offline at once. Private offers expire after 60 days unless the owner confirms. A feed that falls silent raises a flag.
Features
Built for a real local portal, generalised for any WordPress site. Every line below is something the code does today.
Germany & Spain
Choose your market in the settings. Estatequay knows what an ad there must show, holds listings that miss it, and prints the notes on the page in the reader’s language.
Energy demand certificate · Final energy demand 98 kWh/(m²·a) · Energy source gas · Year built 1996 · Energy efficiency class C
Energy rating: consumption E · emissions D · Tourist rental registration no. VFT/MA/12345
The rules follow primary legal sources as of October 2026. They help you get ads right; they are not legal advice.
AI-ready
Switch on one setting and your site serves its listings over the Model Context Protocol. Assistants can search them, read one, and list the agents. Read-only, and only what the public page already shows.

FAQ
Estate + quay: the harbour where listings arrive, from agents’ software and from private owners. Say it like “estate key”.
Yes. Estatequay is licensed under the GPL-2.0-or-later. There is no paid edition, no licence key and no feature held back.
Not yet. Until then, download the zip on this page. WordPress will not update it automatically: check this page for new versions, or use the stable link to the latest zip.
No. Your editors can enter private offers by hand. Agents can join later, with an SFTP inbox for OpenImmo or a Kyero feed URL.
Anything that exports OpenImmo, the German standard most agency software speaks, or Kyero v3, the open format of Spanish portals. A test inbox lets an agent check the first export without publishing anything.
WordPress runs anywhere, and so does the plugin. The built-in ad rules cover Germany and Spain; you choose the market in the settings.
Yes. Your theme renders the frame and the title; Estatequay fills the content area of the listing page and loads its small stylesheet only on listing pages.
No. The contact form fights spam without cookies (a hidden field, a link limit and a rate limit), and agents’ statistics count enquiries, not visitors.
No. The ad rules follow primary legal sources and help you get ads right, but the responsibility for an ad stays with the site and the provider.
On the property page of ebersheim.de, the village portal Estatequay was first built for.
