Getting Started
Umbraco Cloud is the easiest and fastest way to use Umbraco yet, with full support for all your custom .NET code and integrations. You're up and running in less than a minute, and your life will be made easier with automated upgrades and a built-in deployment engine. We offer a free 14-day trial, no credit card needed.
If you want to DIY, then you can download Umbraco either as a ZIP file or via NuGet. It's the same version of Umbraco CMS that powers Umbraco Cloud, but you'll need to find a place to host it yourself, and handling deployments and upgrades will be all up to you.
