Linux Foundation Europe invites you to submit session proposals for the inaugural Open Source Policy & Ecosystem Forum, taking place on 8 June 2026 in Brussels.

This forum is designed as a high-trust, single-track environment (under Chatham House Rule) where the builders of global open source projects meet the architects of European policy. We are looking for sessions that move beyond high-level theory into practical, actionable insights that will support data-driven policymaking. 

What we are looking for: We are seeking technical leads, policy experts, and industry pioneers to present on:

Enabling the Sovereign Stack: Case studies on building European infrastructure using global open source components.

Regulation in Production: Real-world impact of the CRA, AI Act, NIS2, and other key European policies on project maintenance and commercialization.

Strengthening European open source industry and commercial open source: topics related to SME and industry usage of open source and success stories of collaboration (no product pitches)

From European to Global: Ideas for increasing European participation, influence, and leadership of open source project communities across the globe.

Over the past year the MCP project has quickly reshaped how developers are building AI agents, introducing a critical layer of standardization, and a blueprint for how LLMs can interface with applications and tools. The MCP Dev Summit will bring together MCP co-founders and contributors working on the future of MCP project with developers using it to build the next generation of AI agents.

ArgoCon is designed to foster collaboration, discussion, and knowledge sharing on the Argo Project, which consists of four projects: Argo CD, Argo Workflows, Argo Rollouts, and Argo Events.

KeycloakCon is a half-day single-track conference that brings together the Keycloak community. The event offers a platform for technical talks, professional growth, and networking opportunities. Attendees will gain insights from Keycloak developers and maintainers, explore the latest features and updates, and learn from real-world use cases. This is a valuable opportunity to engage directly with Keycloak experts and fellow users, deepening your understanding and expanding your network.

• The actual speaker(s) do not need active maintainer status but should be contributors to the project.
• Sandbox projects are not eligible for maintainer track sessions.

All Others

To submit, you must be a chair or technical lead of a CNCF TAG, a lead for a Kubernetes SIG, CNCF or K8s Working Group.

A maximum of 5 speakers total are allowed per Maintainer Track session.

CHOOSE ONE (1) TRACK

OSS is an umbrella event for open source projects and developer communities to come together under one roof for important collaboration and education.

You will be asked to select the "track" in which you’d like to submit. Each proposal may be submitted to only one track, so please review all carefully before making your selection. We understand that some proposals may fit into multiple tracks. Don’t worry, our program chairs are working together to move proposals around as needed for additional review.

NO PRODUCT PITCHES PLEASE

Please be sure your submission focuses on open source embedded technologies and/or projects, not products specific to your company. We will not select any talks that look like product or vendor pitches.

OPEN SOURCE ONLY

As this is an open source event, talks submitted based on closed or proprietary systems will not be reviewed.

KubeCon + CloudNativeCon + OpenInfra Summit + PyTorch Conference China 2026 will bring together the OpenInfra, cloud native, and AI communities in Shanghai, China. This flagship event unites adopters, technologists, and community members from across the region to drive innovation in open source infrastructure, cloud native computing, machine learning and next-generation AI around common, industry-wide use cases.

Over two days, CNCF Projects, OpenInfra and PyTorch communities will collaborate across dozens of open technologies—including three of the most active open source projects in the world: Kubernetes, OpenStack, and PyTorch—to help shape the future of open source software and technology as a whole.

Grid operators have to deliver affordable, reliable, safe, clean energy, and they need digital infrastructure to do it. Across the sector, utilities and vendors are increasingly turning to open source as the proven way to co-develop the shared, non-competitive building blocks required to modernize the grid faster, at lower cost, and without dependence on single-vendor roadmaps.

LF Energy Summit Europe convenes utilities, grid operators, technology vendors, energy companies, policymakers, researchers, and practitioners to showcase how open source is being used today to build production-grade digital infrastructure for energy systems. The event highlights recent project developments, emerging innovations, and practical lessons from organizations shipping real code, not just ideas.

Attendees will gain insight from leading experts and practitioners into best practices, tools, and technologies; learn how to participate in and scale open source communities; and connect directly with the peers and leaders who are developing the digital grid together.

After a span of several years, the Cloud Foundry Summit returns to a two-day format. We are excited to host our community of end-users, platform practitioners, contributes, maintainers, and industry thought leaders together under a single roof. 

In the intervening years the Cloud has altered tremendously to the point that the cloud abstraction might not exist. In a future dominated by Agentic AI, enabled by declarative infrastructure all cloud abstractions could very well become extinct. Yet, we see a growing presence of Cloud Foundry. We see newer communities come together and solve problems that the CF community solved well many years ago. Come and join us for an event that showcases planet-scale technology which aims to make a mark in a crowded cloud space.

The OpenSearch community is coming together again to learn and connect about all things search and analytics at OpenSearchCon. The event is in-person only, and there is no fee for speakers to attend. This three-day event is designed to bring together builders from across the global community to celebrate the success of the OpenSearch Project and look to the future of search, analytics, and generative AI.

Suggested Topics
Search & Apache Lucene: Connect with other search and relevance practitioners with demos, deep dives, or new and novel techniques for building rich search applications. Master Lucene, the search engine library that powers OpenSearch - from relevancy tuning and efficient matching to analyzers and scoring.

Analytics, Security, and Observability: Deploying observability tools at scale? Using OpenSearch to turn log data into insights, or to help protect your infrastructure? We want to hear from you!

Community: Engage a community of builders on a topic that means something to you. Anything that might educate and inspire a community of open source technologists is up for consideration here.

Operating OpenSearch: Have you have built out an implementation of OpenSearch? Do you use OpenSearch in a solution that helps your own business or project? Share how you operate OpenSearch.

To encourage open collaboration and stimulate discussions that will help advance open source adoption and drive the automotive industry forward, we invite our members, developers, and industry experts to submit a speaking proposal for the AGL All Member Meeting Europe 2026, taking place in Berlin, Germany. AGL Members and Invited Guests provide sessions at AGL’s All Member Meeting.
