KoBoToolbox is free and open source software that can be installed on any computer or server. The vast majority of users use one of two options: The Humanitarian Server hosted by UN Office for the Coordination of Humanitarian Affairs (OCHA) (https://kobo.humanitarianresponse.info) or the Non-Humanitarian Server hosted by KoBoToolbox (https://kf.kobotoolbox.org). The use of KoBoToolbox on either server is free to everyone, but there are certain differences and limitations you should know:
Anyone working for an organization providing humanitarian assistance is free to use the Humanitarian Server provided by OCHA.
If you're using the Non-Humanitarian Server and plan to exceed the monthly submission or storage limits, please email firstname.lastname@example.org to discuss feasibility and potential extra costs.
A very important thing to keep in mind is that sharing projects and data between the two servers is not possible. This means all users working on a shared project need to be using the same server to do so.
