arso is an open project to research and build tools for the decentralized preservation and exploration of information and media.

Today, a lot of our information, our media and our history is stored and managed by large tech companies like Google or Facebook. We think this has to change. It's not only a question of trust and privacy. The question also is how to ensure the independent availability of our collections in the future.

We're developing tools to make it easy to share media collaboratively without relying on centralized services. Instead, we aim for networks of likeminded individuals and institutions that help each other with keeping things online.

Current projects


Sonar is a p2p database and search engine running on top of the dat stack.


Our first app. Think of it as a peer-to-peer cloud storage with more to come. Usable as a web or desktop app. Funded by the Prototype Fund. We are working on version 2 which will be based on Sonar.


Bermuda is a community project to build a sustainable archive of open media from grassroots initiatives and social movements.

arso for ...


With Archipel, we're developing a tool to share material in a future-proof way. We envision Archipel to be used to store, share and collaborate on collections of texts, audio recordings, videos and other data.


We work with the Dat stack, a modular open source stack of peer-to-peer enabled data structures and protocols.


Our peer-to-peer tools make it easy to mirror collections. Redundancy and automatic copying increase the security of your data. Planned features make it easy to find items in collections.


Go share your stuff! Share it with anybody you like, in a private and secure manner, without anybody else knowing aboout the shared content.
