<p>We present <a href="https://howtheyvote.eu">HowTheyVote.eu</a>, a free and open-source website that makes roll-call votes in the European Parliament more accessible and transparent. We briefly showcase the site’s features and how we built it, focusing on the different official data sources we combine. We will discuss good and not-so-good practices of the European Parliament’s websites and take stock of what we learned from four years of scraping parliamentary data. Lastly, we present examples of <a href="https://howtheyvote.eu">HowTheyVote.eu</a> data being used in journalism, research, and civil society, showcasing how accessible voting records can inform debates and thus ultimately strengthen European democracy.</p>
<p>The European Parliament is the only directly democratically elected EU institution, and, as such, the voting behavior of its members is of particular interest. With a significantly larger number of right-wing MEPs since last year's elections, keeping an eye on the developments in Parliament has become more important than ever. Although the Parliament publishes information such as roll-call vote results and plenary minutes on its website, it can be difficult to find out what exactly MEPs voted on or how a particular vote turned out, as the data is scattered across multiple sources, published in different formats, and made available at different times.</p>
<p>We started <a href="https://howtheyvote.eu">HowTheyVote.eu</a> in 2021 as a free and open-source project to address these problems. On <a href="https://howtheyvote.eu">HowTheyVote.eu</a>, users can search for votes and view results. We also publish our entire <a href="https://github.com/howTheyVote/data">dataset</a> under an open-data license.</p>

<p>European digital sovereignty is moving from slogan to strategy. Faced with dependencies and in line with its resilience goals, the EU increasingly turns to open source as a pillar of its technological autonomy. Yet the debate often stalls on the questions: Where is software “made”? Who “owns” the code? And can sovereignty be achieved simply by adopting European-labelled alternatives? - all questions that often are not compatible with how open source actually works, and potentially ...

<p>Europe’s IT landscape has long been heavily reliant on just a few large American tech providers, and this is equally true for the systems used in public administration. This dependence jeopardises the administrative services that underpin our states’ functioning. To counter this, Europe needs a tech stack that strengthens digital sovereignty at every level, from databases and virtualisation to operating systems and end-user applications. </p> <p>Various governments and governmental ...

<p>As it takes a village to raise a child, it takes a global open ecosystem to build a Euroshack. Inspired by the Frugal Manifesto, we envision the Euroshack as the first agile prototype of a truly open EuroStack: modest in form, ambitious in purpose. Grounded in pragmatism and powered by free and open software, the Euroshack avoids nationalist overtones and instead champions a scalable, dependable core. “Shack” is a humble name, but it reflects a bold mission: to secure digital sovereignty ...

<h2>Abstract</h2> <p>Europe has bold ambitions for open source and digital sovereignty, yet most initiatives struggle to deliver meaningful change where it matters: at the level of local institutions. Despite strong strategies and political commitments, implementation stalls because the policy frameworks guiding European digital transformation ignore a simple truth. Europe is built on a multi-level governance system where local actors carry the responsibility for execution but lack the ...

<p>Roundtable discussion with policymakers and the community: how can the public procurement framework, that is currently being reformed, be used to achieve digital sovereignty goals? Open Source provides many answers to the questions digital sovereignty raises, but how can public procurers be empowered to buy more Open Source, what are their expectations, and what hurdles exist?</p>

<p>A Blueprint for Trusted European Digital Services</p> <p>The European Commission’s Cloud Sovereignty Framework (Version 1.2.1, Oct. 2025) is a critical blueprint for defining, assessing, and ensuring the sovereignty of cloud services used within the European Union. Born from initiatives like Gaia-X, CIGREF's Trusted Cloud Referential, and EU legislation (NIS2, DORA), this framework supplements security requirements with sovereignty-specific safeguards to reduce dependency on non-EU actors ...
