We currently offer a $0.99 24-hour access trial that begins upon purchase for our Managed Server plan. This plan comes with pre-installed software geared towards allowing users to develop and publish applications.
We also offer a $0.99 48-hour trial for our VSTS Agent plan. This plan is best for Visual Studio Team Services (VSTS) users to set up Continuous Integration. If you are seeking remote build capabilities for Visual Studio 2017 and Xamarin, you should instead choose the Managed Server plan with the "Enable Remote Build Port" add-on selected at the time of checkout.
