Open Source Summit: India 2026
2026-06-16 - 2026-06-17
Open Source Summit is the premier event for open source developers, technologists, and community leaders to collaborate, share information, solve problems, and gain knowledge, furthering open source innovation and ensuring a sustainable open source ecosystem. It is the gathering place for open-source code and community contributors.
Open Source Summit is not a single-focus, niche event—it’s the big tent that unites the full spectrum of open source technologies and communities. Whether you work in cloud infrastructure, Linux kernel development, AI/ML, embedded systems, DevOps, security, or safety-critical systems, Open Source Summit offers a shared space to exchange ideas, make connections, and learn across domains. It’s where technologists who don’t typically land in the same room get a chance to collaborate.
At the same time, Open Source Summit brings in the leaders and practitioners who support the ecosystem from non-technical angles: open source program office (OSPO) staff, legal experts, policy advocates, standards organizations, equity champions, community managers, and foundation leaders. Together, they help shape the frameworks, culture, and strategy that make open source work.
This event serves as a strategic checkpoint for the open source movement. It’s where conversations happen about not only what’s being built—but how and why. From sustainability and funding models to licensing, AI alignment, security, and governance, Open Source Summit brings clarity and direction to a fast-changing open source landscape.

LF Energy Summit Europe 2026
2026-09-15 - 2026-09-16
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.
If you are working with Zephyr RTOS in energy-related use cases, this is a great opportunity to join the conversation—submit a talk proposal and share your insights with the community.
Submit your talk proposals soon. CFP Closes on Monday 25 May at 11:59 PM CEST (UTC+2) / 2:59 PM PDT (UTC-7)
