Cloud-based vs Self-hosted Kobo

Hi KoBoToolbox users

For data security reasons, we’re looking at installing the self-hosted version on our own servers. Can anyone help with any or all of these questions?

  1. Is the self-hosted version more or less user-friendly than the cloud version?
  2. Are updates regular?
  3. Is it easy to import forms made for the cloud version?
  4. Is the API (for editing/reporting) the same? (we’ve made a tool to do this on the cloud version and would like to use it on the s-h version, once installed
    Many thanks
