The Public Stack in practice

Building for the Public Stack starts with the many initiatives and technologies that are out there already and which are built according to, and driven by, the same general considerations that we have outlined here. And there are many. Technologies, collectives, programmes and initiatives; working on the Public Stack can take many forms. For a large compiled list of technical solutions that are public and open source check

We highlight a some building blocks and initiatives here; a necessarily short, subjective and totally incomplete list.


In rapidly digitizing cities, ethical and responsible use of data is a major challenge – and Amsterdam is no exception. 

Professionals from the Amsterdam region therefore wrote a manifesto entitled ‘Tada – data disclosed’. Government authorities, companies and other organizations from different regions are invited to use and sign the document, showcasing their ambitions to shape a responsible digital city.

PublicSpaces are reclaiming the internet as a force for the common good and advocating a new internet that strengthens the public domain. Read our manifesto to see the values we want to see at the core of our digital lives. PublicSpaces are adopting and supporting the development of a software ecosystem that’s based on the values defined in the PublicSpaces manifesto. The goal is ultimately to accelerate the development of an alternative software ecosystem that serves the common interest and does not seek profit.

Raspberry Pi

The Raspberry Pi is a series of small single-board computers developed in the United Kingdom by the Raspberry Pi Foundation to promote teaching of basic computer science in schools and in developing countries. The original model became far more popular than anticipated, selling outside its target market for uses such as robotics. It is now widely used even in research projects, such as for weather monitoring because of its low cost and portability.
