EU
OPEN
SOURCE
WEEK 2026

The “event” is meant to coordinate several train routes to Brussels to bring hackers from all over Europe to FOSDEM and the Open Source Week. The intent is on both helping hackers organise their travel and being a means for meeting and socialising in smaller environments (trains) before reaching the main event that is FOSDEM.

The start date is just a guesstimate when the earliest HackerTrains will leave for Brussels. It is entirely up to the routes/groups to decide when they travel.

During the session, the Open Social CEO will highlight how ECP SaaS empowers organisations to create public, private, or hybrid communities. As a solution built on Open Social (Drupal), ECP SaaS leverages the open-source ecosystem to foster collaboration through contributions, such as patches, new modules, improved documentation, and innovative ideas shared at DrupalCon.

During the two-day event, developers, designers and other digital innovators will work side by side to create smarter, faster and more open digital solutions built with Drupal and AI.

Drupal Pivot is a 1.5-day, peer-led un-conference for Drupal agency CEOs, founders, and senior executives to collaboratively explore the most pressing strategic questions shaping the future of the Drupal business ecosystem. Rather than a preset program, the agenda is created by attendees at the start of the event, ensuring the conversations directly reflect your real-time challenges, priorities, and opportunities.

In this webinar, Stephen Abbott Pugh will talk about the 2024 EU AML package, what it means for better understanding who owns and controls European companies, and how using an open standard such as the Beneficial Ownership Data Standard would help much more to achieve the goals set out in the package

Digital Sovereignty, Competitiveness and Cybersecurity are key policy objectives of the EU. To achieve these goals, the next MFF must allocate resources to Open Digital Infrastructure – open source technologies that form the basis of Europe’s key industries and public services. The study shows how the successful model of the Sovereign Tech Agency can be scaled to the European level.

There any many vulnerability databases, both commercial and freely available, that provide critical data for keeping our systems and products secure. The main free ones, CVE and NVD, has experience problems during the last year which creates a lot of uncertainty. The community works together to both ensure continuos availability of freely available vulnerability information as well as agreeing on a long term plan for the governance of these systems. The GVIP Summit is the place to meet and discuss where we are and what we want in the future. Welcome!

The 2026 edition will serve as a moment to take stock of progress achieved over the past decade and to translate the lessons learned into an agenda for 2026–2030. It will bring together partners from across research, education, culture, the private sector, and public administration to consolidate a shared vision in which software preservation, citation, and reuse are integral to knowledge creation and dissemination. While the event is hybrid, the physical attendees are expected in Paris, France.

The event will feature presentations from the European Commission’s Open Source Programme Office (OSPO) and from the authors of the latest OSOR reports on trends and progress within public sector open source on a local and national level, as well as a practical handbook on open source implementation. OSOR will also host representatives from Barcelona City Council, the first city to adopt the UN Open Source Principles. Arnau Monterde Mateo, Director of Participation and Innovation, will present Barcelona’s strategy and will also host a debate on the city’s transition and upcoming “Open Tech Week 2026”

Everyone is invited on a first come first served basis. Enjoy the stunning views of Brussels at night and Free Beer and Wine. Network, relax and mix with those shaping and influencing regulation and those representing open-source software development in Europe.

The event is organised by Comply.Land and Open Regulatory Compliance Working Group

This event is invitation only.

Our goal is for open source developers, users, and contributors to exchange requirements, plans, and collaboration opportunities around FOSS tools for software provenance detection, vulnerability management, license detection and regulatory compliance like CRA, code scanning, package dependency analysis, container analysis, SBOM creation and consumption, and license or vulnerability databases – basically, all the tools you need to figure out which FOSS code you use, where it is from, what is its license, how to comply with the license, and whether it contains vulnerable code.

Previous attendees include developers from ORT, ScanCode, ClearlyDefined, FOSSology, Tern, FSFE REUSE, SW360, BANG, Hermine, Opossum, SPDX tools, DoubleOpen, OpenChain, and AboutCode projects along with users from leading technology and industrial companies, open source foundations, and government institutions worldwide. Whether you are a developer or user interested in the tools for Software Supply Chain and SBOMs, a FOSS license-savvy lawyer, a compliance or security analyst, or an OSPO member: you will be warmly welcomed.

During the first hour, people will list what they want to work on, and form teams on the spot. Every project helps us fill our experience bar. Our skills increase when we work on anything related to Matrix. After the project presentations, we will stay in HSBXL in the evening for a public Matrix Lounge Evening. We’re inviting the entire Matrix community to spend a relaxed evening with food, drinks and interesting discussions about Matrix! We’re asking all hackathon attendees to register so we can best organise the event.

Europe is confronting fundamental questions about its digital sovereignty — a concept that now encapsulates the full range of its strategic challenges: competitiveness, market concentration and dependency, and systemic resilience. The 2026 edition of the EU Open Source Policy Summit will bring together leaders from the public and private sectors to focus on one clear proposition: open source delivers digital sovereignty.

The EU Open Source Policy Summit is set for 30 January 2026 in Brussels and will be accessible online.

Community collaboration is at the heart of OpenTelemetry. With OTel Unplugged, we’re launching what we hope will become a regular series of unconferences where project maintainers and community members come together in person to share knowledge, provide feedback, and help plan the project’s future.

Unlike traditional conferences, there are no predetermined talk tracks. Attendees propose and vote on topics, ensuring the agenda reflects the conversations you want to have. The day begins with a project update, then flows into breakout sessions where contributors, end users, and maintainers exchange ideas and tackle real-world challenges. Each group shares key takeaways with the wider community, building shared understanding.

Who should attend:
* Developers of Linux distributions for embedded devices, containers and related products
* People working with OpenEmbedded and the Yocto Project
* Manufacturers providing software support for embedded Linux devices
* Software developers deploying application to embedded devices
* Security professionals interested in learning more about embedded software practices

This time it is going to be very hardware-focused,as well as we started open sourcing our AI hardware.

​​This event is a continuation of the DevRoom to have more time together in a more relaxed atmosphere. Expect hands-on sessions not just talks. Bring all your questions, unresolved issues and unaccepted PR requests. ​

Configuration Management Camp will have a main track, hacker spaces, training, workshops, and keynotes. The schedule will be posted once it has been finalised.

​​As real-time databases integrate more closely with data lakes to reduce storage costs and unlock data for AI and advanced analytics, data infrastructure is evolving fast.
