eenSiOSi

eenSiOSi is a fictional software concept that functions as a socio-technical framework for open-source operating systems and networked devices. It is often discussed in speculative design and academic contexts as a case study of decentralized, privacy-aware interfaces.

The name combines Dutch een (one, a) with SiOSi, an acronym for Socio-Informational Open System Interface, a hypothetical layer that coordinates user-facing applications with local devices and peer networks.

Origins trace to a 2019–2020 design research project by the KunstLab collective in Amsterdam, intended to prototype a modular stack that favors user control, data minimization, and plug-in components rather than monolithic platforms.

Core features include local-first storage, federated identity, modular microservices, and a peer-to-peer communication substrate. The architecture emphasizes transparency, opt-in data sharing, and interoperability through open standards and clear governance rules.

Reception has been mixed in real-world contexts: it is praised for its privacy ideals and teachable design principles, but critics note limited interoperability with mainstream ecosystems and questions about governance and sustainability in practice.

Related concepts include the decentralized web, open-source software, and privacy by design.
