Product Overview

Add On IDX is a JavaScript-based IDX solution that hooks MLS data from 450+ boards into almost any web platform—making it a strong pick for agents and designers using Webflow (where it holds Premium Partner status), Squarespace, or Wix, not just WordPress. It ships with map search, lead capture forms, saved searches, market reports, and a mobile app, at a $149/month starting point that undercuts full website platforms but costs more than dedicated WordPress plugins like IDX Broker or Showcase IDX. Month-to-month billing is a genuine advantage over contract-locked competitors. The friction points: MLS paperwork approval adds a 1–7 day delay before going live, no demo accounts can be provisioned due to MLS rules, and the widget customization layer stops at preset themes plus CSS. Brokers who need a fully hosted IDX website rather than an embeddable widget should look at RealSavvy or iHomefinder instead.
