We found 21 Digital Infrastructure (DI) projects developed and/or maintained by 12 cooperatives located in 7 countries: Argentina (3), Canada and India (1), Spain (1), USA (2), France (2) and England (3). The DI they develop and/or maintain is part of the Composer, Wordpress, Ruby, React, Redux, Vue, Symphony, Python, Django, Drupal and the Solid web standard ecosystems, and consists of: libraries, tools, frameworks, modules, an API, a protocol and time and billing management platforms, as well as a CMS distribution. All projects are licensed under FLOSS. The vast majority of these DI projects have been initiated by the cooperative, but not all. In the cases in which they have not started the project, they have supported the founders in its subsequent development and maintenance. The DI they develop is available in 5 open online repositories. All of these DI projects have contributors outside the cooperative forming a development community. This community is made up of freelance programmers, students, workers from other companies and independent consultants as well as different types and sizes of public and private organizations. In turn, those who use the DI are also companies and organizations of different types and sizes, as well as freelance workers, enthusiasts and students who benefit from it without necessarily requesting their service to the cooperatives.
