Overview

OpenDataKit (ODK) is a free and open-source set of tools that helps organizations author, field, and manage mobile data collection solutions. It is the foundational technology upon which other tools like KoboToolbox are built. Using ODK involves setting up a server (like ODK Central) and using mobile apps (like ODK Collect) for data entry. It is highly powerful and customizable, but requires more technical expertise to set up and manage than hosted solutions. It is a go-to choice for organizations that require full control over their data and infrastructure.
