we are free to share code and we code to share freedom

Welcome to our digital community and free software foundry is a non-profit free software foundry with almost 20 years of expertise in developing applications used worldwide.

Code repository

Code is our literature: we build software to communicate, interact and inspire. We let art, science and technology meet open source.


We welcome donations and cooperation proposals for projects that benefit human society and respect the natural environment.

Selected projects

Interfacer: Digital Infrastructure for Fab Cities, Regions and Nations

Fab(rication) City concept of distributed production of open-source hardware and distributed design processes for building a digital infrastructure enabling ecological, economic and social sustainability. In cooperation with FabCity.Hamburg.

Quantum-Proof crypto made easy and portable

We like to develop systems that last long in future, that’s why we work on quantum-proof (qp) resistance in our software.
And now we have qp in Zenroom for signature and verification!
Zenroom makes it very easy to add quantum crypto in your own application, using NIST approved standards .
This development has been funded by NGI Assure and NLNet.

Co-creating circular and regenerative resource flows in cities

EU H2020 funded project that seeks to understand and transform urban material flows, co-create and test regenerative solutions at business, governance, and citizen levels to create a resilient circular economy. Our contribution consists in developing the ReflowOS operating system, for communities who want to create federated and secure economic networks to foster the creation and coordination of distributed value chains. Check out the architecture and the manual for distributed network setup and maintenance.

Zenroom: easy cryptography to the people

Zenroom is a tiny and portable virtual machine that authenticates and manages access to data using human-readable smart contractsZenroom is easy to program to performs fast cryptographic operations for end-to-end encryption and runs on: desktop, embedded, mobile phones, clouds and web browsers.

DECODE reclaims technological sovereignty.

The DECODE project is a the first EU research project on blockchain technology and one out of two to become a flagship project for the EU Commission. We are proud to be its technical coordinators and to lead a fantastic consortium towards its outstanding success. Dive into DECODE’s research materials and browse the software we have developed.


Devuan GNU+Linux is a very stable free software operating system for PC, +40 embedded ARM boards and cloud micro-services. This distribution has made headlines worldwide and its community-based developed is driven by large numbers. Join the FORUM – Download the ISO – Learn more about Init Freedom.

Decentralized Citizen Engagement Technologies

D-CENT is a research and development project on privacy-aware tools and applications for direct democracy and economic empowerment. Together with large movements of citizens and developers, we build decentralized social networking platforms for participatory democracy, collaboration and decision-making.

Museum of Working Computers

Since more than 20 years we curate a museum of working computers: a place where people can, both physically and remotely via Internet, log into historical computers, know their history and learn electronics and computer science starting from the beginning. We repair, preserve and share to the public our heritage: hardware, manuals, software, electrical schemes and media of various kind.

18 Think &Do Tank

We facilitate artists, creatives and engaged citizens in the digital age, sharing tools, practices and narratives for community empowerment.
Our software is not just about market products to satisfy consumer needs: it has implications that can be aesthetic, social, political, technical, spatial, linguistic, economic and numerical.
Since the year 2000 a large amount of people and organizations employed and redistributed our creations: radio makers, film makers, artists, medics, activists and educators.
Our strengths are community, software and documentation.
Worldwide, free of charge, free to copy.

We work also as an European research organisation for the delivery of publicly funded software projects and we believe that code paid by the people should be available to the people. Our software gives everybody the right to use, study, share and improve its code, to support fundamental freedoms like freedom of speech, press and privacy. is associated to the Free Software Foundation Europe (FSFE) and involved in the following research grants:

 All grants above adopt, promote and produce exclusively Free and Open Source Software and we are very proud and well committed to encourage this ethical practice across public institutions and the European research community. Social Network

@jaromil di @DyneOrg: va eliminata la dialettica conflittuale. O si punta sulla consapevolezza o "saremo condannati a vivere in guerra con le macchine, con gli altri e con noi stessi"
Di Alessia #Valentini su @Cybersec360
Is #ETH2 increase of efficiency at cost of centralization "good for the environment"? No. We need to use cryptography and math to actively develop for the aims of a green and sustainable agenda. We are doing our best here, rather than on crypto markets:
