This is a partial listing of genealogy software developers, both companies and individuals, as well as publishers. Some of these companies/developers focused on one or two applications, others are companies with dozens of products under their portfolio. A few genealogy applications were worked on by multiple companies over the years, and all relevant companies are listed below. Contact us if you have any additional information or corrections, as a lot of the information/events before the mid-1990s is hard to come by.
