Umbraco CMS is open-source, free to download, and use for any web application. There are also many hundreds of add-on packages that have been written by the community for extending the functionality of Umbraco.
Umbraco is completely committed to the Open Source model for its core Content Management System and has always maintained to remain free forever.
This means that a large proportion of the Total Cost of Ownership of a website is substantially reduced, making it a tool well-suited to business, academia, and the not-for-profit sector.
Alongside the free CMS, Umbraco also sells a number of paid plug-ins for Umbraco including Umbraco Forms and Courier. Umbraco also draws revenue from services such as hosting on Umbraco Cloud and Training and Support Services, and their paid Partner Programmes.
Costs will inevitably vary from build to build due to different business' requirements such as the scale of the application and the functionality you need. If you'd like to understand how much your next Umbraco project may cost then contact us for a quote.
