Is Zillow Exporter safe?

Zillow Exporter hooks Zillow's search API to capture full listing records, including agent names, phone numbers, and emails.

On www.zillow.com the extension replaces the page's own fetch and XMLHttpRequest functions to read Zillow's search and GraphQL API responses as you browse. It parses each listing into a record, including the listing agent's and broker's name, phone, and email along with address, location, and Zestimate, and stores them in the browser for bulk spreadsheet export. It also rewrites outgoing search requests to ask Zillow for more listing data than the page originally requested; the collected data stays in local browser storage rather than being sent to an outside server.
