About EuroStack
Welcome to the EuroStack Directory Project – Your Gateway to European Digital Solutions
The EuroStack Vision
The EuroStack (sometimes spelld "Euro Stack") a strategic blueprint for a comprehensive, sovereign, and interoperable European digital infrastructure. It is not a single product but a complete technological ecosystem encompassing all layers of the digital value chain, from the foundational physical infrastructure — such as semiconductors (chips), compute (cloud, data centers), and connectivity (networks) — to the logical infrastructure of software, platforms, AI frameworks, and data spaces. The core purpose of the EuroStack is to establish European technological independence by federating and enhancing Europe's existing technological assets and capabilities into a cohesive ecosystem built on a foundation of Open Source and open standards, thereby reducing strategic dependencies and ensuring Europe's security, competitiveness, and digital autonomy.
The EuroStack Industry Initiative
The EuroStack Industry Initiative is a movement and informal, non-lobby group comprised of over 200 European digital and technology CEOs, industry participants, tech specialists, economists, and advisors, as well as think tanks, academics, and civil society organizations. The participants contribute in their personal capacity as volunteers.
It was formed out of a shared concern for Europe's growing dependency on non-European digital infrastructure and the decline of its own digital capabilities.
The initiative's plan to achieve European digital independence is built on four core pillars, as detailed in its white paper "Deploying the EuroStack: What's Needed Now":
-
"Buy European": To drive demand for European technology by transforming public procurement rules to prioritize European suppliers and by creating targeted incentives (e.g., tax credits, certifications) to steer private sector demand towards European solutions.
-
"Sell European": To enhance the visibility, cohesion, and competitiveness of Europe's digital industry by establishing a Market Intelligence Hub, fostering ecosystem collaboration for integrated solutions, and addressing the skills gap.
-
"Fund European": To mobilize public and private capital to address the funding gap for European tech companies. The central proposal is the creation of a dedicated "EuroStack Fund" that co-invests with the private sector to catalyze growth.
-
Embrace Openness: To establish "Openness" as a core, cross-cutting principle for the entire digital ecosystem. This involves championing Open Source Software, mandating enforceable open standards and data portability, and stimulating other digital public goods (like open data and open models) to prevent vendor lock-in and foster collaborative innovation.
The EuroStack Directory Project (ESDP)
What It Is
The EuroStack Directory Project is a comprehensive directory of European-made and European-supported digital solutions, including cloud services, Open Source technologies, and interoperable tools. Our mission is to promote European technological sovereignty by connecting businesses, and public organizations with solutions designed to align with European values of transparency, privacy, and sustainability.
The ESDP is fully aligned, and cooperates, with the EuroStack Industry Initiative on implementing the EuroStack Vision.
Our Vision
We envision a Europe where digital infrastructure is not only innovative but also independent and aligned with the continent's ethical and legal frameworks. By highlighting solutions that prioritize interoperability, openness, and European support, we aim to foster an ecosystem that:
- Reduces reliance on non-European technology.
- Encourages collaboration between public and private sectors.
- Advances digital commons and Open Source innovation.
More details about our vision and values can be found here.
What We Do
The EuroStack directory provides a trusted platform to discover:
- European Cloud Services: Explore providers that offer secure, scalable, and GDPR-compliant cloud infrastructure.
- Open Source Technologies: Find robuste and innovative software solutions built on transparency and collaboration.
- Interoperable Tools: Identify tools and platforms designed with standards that ensure seamless integration and avoid vendor lock-in.
We offer curated listings, detailed information, and resources to help organizations and individuals make informed decisions about adopting European solutions.
More details about our ambition and goals can be found here.
Why EuroStack?
- Strategic Digital Sovereignty: We prioritize solutions that are developed, hosted, or significantly supported within Europe. This ensures alignment with European regulations, data protection standards, and strategic interests, providing businesses with greater control and legal certainty.
- Driving Innovation Through Openness and Interoperability: We champion Open Source technologies because they foster innovation, transparency, and flexibility. Openness enables customization, reduces vendor lock-in, and accelerates development, while interoperability ensures seamless integration and data exchange across different systems.
-
Trusted, Transparent, and Secure: Every solution listed on EuroStack undergoes a rigorous vetting process to ensure it meets the highest standards of quality, security, and privacy. We prioritize transparency and alignment with European digital strategies, providing businesses with reliable and trustworthy solutions they can depend on.
- Security by Design: Open source code allows for continuous security auditing by a global community of experts, making vulnerabilities more readily identifiable and fixable, creating a more secure solution over time than proprietary code.
- Transparency and Trust: The open nature of the code used in EuroStack solutions allows any business to inspect and verify the software they use, promoting trust and accountability.
- Empowering European Businesses: EuroStack is committed to building a robust and competitive European digital ecosystem. By providing access to high-quality, sovereign, and interoperable solutions, we empower businesses of all sizes to thrive in the digital age.
How Does It Work?
We currate and categorize European digital solutions based on their relevance, features, and compliance with European standards. Users can explore listings, read detailed descriptions, and connect with providers directly to learn more.
To identify the solutions we showcase, we use various open data sets, including:
- Awesome Free / Open Source Alternatives (to common SaaS products) for Business Use - an extensive exploration of the alternatives available to businesses looking to leverage Open Source solutions.
- AFS ONE - Free Software Publisher Directory.
- Cloud Repo - The comprehensive index of cloud and telecommunication technologies made in Europe
- Awesome Free Software - Your "yellow pages" of Enterprise Free Software Publishers, their products and success cases.
- Guide des solutions open source (in French)
- SILL - Catalogue de référence de logiciels libres recommandés pour l'ensemble de l'administration ( in French)
- Comptoir du Libre - A list of free software useful to the public services as well as their users and providers.
and scout upcoming solutions through forums, social media, and direct contacts with providers.
