Odk

ODK Central is a powerful open-source platform for creating and managing digital forms for data collection. While ODK offers cloud-hosted solutions, many organizations require self-hosted deployments for data sovereignty, custom integrations, or compliance requirements.

ODK is a popular tool for offline data collection with a thriving user community. Like a number of other offline data collection tools, it uses the XLSForm standard for authoring forms. While convenient to author and exchange, authoring the forms in Excel means each iteration of the form must be uploaded to the ODK Central server that distributes forms to mobile data collection applications, such as ODK Collect.
