PropertyWebBuilder

PropertyWebBuilder is a Ruby on Rails application for building real estate websites quickly. It is part of a small family of property-tech products by its author and is positioned as combining CMS and lead-generation features for estate agents and property sites.

Version 2.1, released in December 2025, adds embeddable property widgets that can be placed on external sites as JavaScript or iframes, with customizable themes, colors, layouts, domain restrictions and impression and click analytics. The admin side gained an interactive map location picker for properties, an improved dashboard with quick actions, a setup wizard for new websites and multiple color palettes per theme. Developer improvements include request specs, idempotent seeding and Playwright end-to-end tests. Version 2.0 was a major release representing five years of development.

It is MIT licensed and hosted by you, with Heroku among the topics and an Open Collective page for support. The README also mentions using it together with Cloudflare's EmDash through a separate integration repository.
