OpenTofu Day debuted at KubeCon Europe 2024 in Paris and has been held at every KubeCon since. As the infrastructure-as-code ecosystem reaches a clear inflection point with recent licensing shifts, industry consolidation, and changes to commercial Terraform offerings, organizations are actively evaluating open source, community-governed alternatives. As a CNCF Sandbox project with more than 10 million GitHub downloads, OpenTofu offers a vendor-neutral foundation that the cloud native community can rely on for the long term.
Who will get the most out of attending this event?
DevOps engineers, platform engineers, and infrastructure leaders will benefit most from OpenTofu Day — particularly those running Terraform in production who are evaluating or planning a migration to OpenTofu in 2026. Platform engineering teams building or evolving internal developer platforms will find the sessions highly relevant, as OpenTofu is increasingly becoming a core building block in that space.
The event is also valuable for infrastructure leadership looking to understand the broader strategic implications of licensing shifts in the IaC landscape. Maintainers and contributors who want to get more involved will find this the best single venue to connect directly with the core team and community.
What is new and different this year?
This marks the fifth edition of OpenTofu Day and the project’s first full year as a CNCF Sandbox project. The conversation has moved beyond early momentum and initial adoption toward production maturity and long-term sustainability.
Sessions this year focus on real-world enterprise adoption, including innersource models inside large organizations, OpenTelemetry-based performance debugging for infrastructure runs, and scaling OpenTofu across complex environments. The speaker lineup also reflects a broader and more diverse community, with more end-user enterprises sharing experiences alongside project maintainers.
What will the day look like?
OpenTofu Day is a half-day event featuring keynote-style talks, interactive panels, community experience sessions, and lightning talks. The day begins with a state-of-the-project update covering new features, roadmap direction, and community growth.
An interactive “Ask the Devs” panel gives attendees direct access to core maintainers, followed by sessions that highlight real-world production stories, migration journeys, and novel use cases. Attendees will also have time between sessions to connect with peers in the hallway and continue conversations informally.
Should I do any homework first?
Experience with OpenTofu, Terraform, or another infrastructure-as-code tool will help attendees get the most out of the day. Those who have already experimented with OpenTofu or begun evaluating migration paths will find the sessions especially practical.
That said, prior hands-on experience is not required. Newcomers will still gain valuable context around where the IaC ecosystem is heading and can use the event as an opportunity to connect with experienced practitioners and maintainers.
Find your community!
OpenTofu Day is the most concentrated gathering of OpenTofu developers, contributors, and users anywhere in the world. It creates a space for practitioners to share production experiences, for the core team to hear directly from users, and for new contributors to find their entry point into the project.
The event reinforces the project’s community ownership — built collaboratively under the Linux Foundation and CNCF to ensure infrastructure-as-code remains open, transparent, and governed by its users. Whether you are migrating, scaling, contributing, or simply exploring your options, OpenTofu Day offers a focused environment to learn and connect.
