Most of KubeCon + CloudNativeCon assumes the cluster already exists. OpenTofu Day covers everything that has to be provisioned before and around it: cloud accounts, networking, managed services, and the clusters themselves. On November 9, OpenTofu Day returns to Salt Lake City as a co-located event at KubeCon + CloudNativeCon North America 2026 . It is a single-track day. OpenTofu's core maintainers are in the room from start to finish, and teams running OpenTofu in production share what they've learned.
Licensing changes, consolidation, and shifting commercial models have led many organizations to reexamine the tooling their infrastructure depends on. Many now prefer projects governed by their communities. OpenTofu has grown from a fork into a CNCF Sandbox project with more than 10 million downloads as of October 2026. Recent releases have added capabilities of its own, including client-side state encryption, for_each on provider configurations, and OCI registry support. For most teams, switching the CLI is the easy part: OpenTofu is designed as a drop-in replacement for Terraform.
The bigger decision is what happens to everything around it, meaning the pipelines, state management, policy, and access controls through which infrastructure changes are made. Platform engineers generally choose between two paths. They can keep their existing workflows and swap the engine underneath with minimal disruption, or they can use the migration as an opportunity to re-platform and redesign how infrastructure changes are delivered. Each path has real trade-offs in risk, effort, and long-term flexibility, and the right choice depends on the organization.
Hearing from teams that have taken each path is one of the most useful things OpenTofu Day offers, and it is where that experience gets shared openly. OpenTofu Day debuted as a CNCF-hosted co-located event at KubeCon + CloudNativeCon Europe 2024 in Paris, about two months after the project's first stable release. It has been held at every KubeCon + CloudNativeCon Europe and North America since then, in Salt Lake City, London, Atlanta, and Amsterdam, often to near-capacity rooms.
