Simpl provides multiple open-source components, free to use, that adhere to EU standards and best practices for data quality and data sharing. It offers a modular, open, and reusable foundation that integrates existing solutions rather than replacing them, completing them with additional development where needed. Simpl technically facilitates the set-up of data spaces, helping initiatives to reduce the time and resources needed to select, develop and integrate components. The adoption of Simpl facilitates interoperability between data spaces and initiatives. Thanks to its open-source nature, the community can actively participate in the development of Simpl. Simpl is composed of three main products: Simpl-Open, Simpl-Labs and Simpl-Live.
