The Enketo Smart Paper web application. It can be used directly by form servers or used as inspiration for building applications that wrap Enketo Core. See this diagram for a summary of how the different Enketo components are related.

To get started visit our technical documentation.

Enketo was initiated in 2009 by Martijn van de Rijdt as a web-based alternative or complement to ODK Collect. It has become a core component of the ODK ecosystem and been adopted by several organizations beyond that ecosystem.

As of 2022, Enketo is maintained by the ODK team (primarily Trevor Schmidt). Martijn continues to provide advice and continuity. The ODK project sets priorities in collaboration with its Technical Advisory Board.

Our current primary goals are:

• Increasing alignment with ODK Collect, particularly in service of submission edits.
• Improving error messages so that users can get out of bad states.
• Improving long-term maintainability by modernizing code bases, removing code duplication, and simplifying state mutation.

Feature requests and project discussion are welcome on the ODK forum.
