Open-Realty® is a free web based listing management application. It is intended to be both easy to setup and use. Written in PHP, Open-Realty® is designed to be a fast and flexible tool for your website. With a large open-source community working with this application and solid management from Transparent Technologies, Open-Realty® is the top choice for use on your website.

Open-Realty® is released free of charge and to help support the continuing development please consider using
Transparent Technologies, Inc. for your web hosting provider.
Transparent Technologies, Inc. is owned by Ryan Bonham, the lead developer for Open-Realty®.
Open-Realty® is an open source product and the open source license for Open-Realty® permits you to use the software at no charge under two conditions:
1. You have to leave the html comment that reads "<!--
Open-Realty® is distributed by Transparent Technologies and is Licensed under the Open-Realty® License. See http://www.open-realty.org/oslicense.html for more information.-->" intact.
2. If you use Open-Realty® in an application you redistribute, the complete source code for your application must be available and freely redistributable under reasonable conditions (there is more to read

In my opinion, the most useful and beautiful component for O-R is "
CMS Realty" (project managed by
Codenza Ltd.). CMS Realty integrates the O-R listings management software with Joomla and Mambo. Combining Content Management features with O-R, provides a powerful and flexible website solution for real estate agents, agencies and portals.
