Restack Open Call (2027-01R)
About the grant
Restack will helps deliver, mature and scale operational internet commons across the technology stack to form Connected Collaborative Computing networks (3C): from libre chips to middleware without vendor lock-in, from productivity tools to 'local-first' infrastructure — and of course including end user applications needed to consume those networked services. We are seeking project proposals between 5.000 and 50.000 euro's that help strengthen the open internet stack through such building blocks.
Who can apply
Projects can be submitted through https://NLnet.nl/propose , please check the guide for applicants and our Generative AI policy before you start writing a proposal - this might save you a lot of work. Anyone can apply, including private individuals and organisations of any type, provided that your proposal has a clear European dimension . All outcomes should become available under a free and open license. There is a two stage evaluation process followed by an external review .
How to apply
Apply through the EU Funding & Tenders portal. UK organisations can take part in Horizon Europe on the same terms as EU members. Many calls need a group of partners from different countries.
