About Scalr
What is Scalr?
Scalr is a drop-in replacement for Terraform Cloud, offering full feature parity plus extras like free drift detection and unlimited self-hosted agents. It provides a secure, standardized workflow for infrastructure as code, enabling platform teams to manage Terraform and OpenTofu at scale.
What problem does it solve?
Scalr addresses the high costs and concurrency limitations of Terraform Cloud. With usage-based per-run pricing, there are no per-user fees or concurrency slot charges, so you only pay for runs that actually execute. This lowers the total cost of ownership while providing better GitOps support, such as PR-native automation and branch-aware state protection.
Who is it for?
Scalr is built for platform engineers who need to build and manage a self-service platform for developers. It is ideal for teams migrating from Terraform Cloud who want to reduce costs without sacrificing functionality. It may not be suitable for small teams with very simple infrastructure needs who don't require advanced policy or governance features.
Real use cases
Scalr is used by teams to manage multi-environment infrastructure, enforce policy as code with OPA or Checkov, and provide developers with self-service workflows through vending machines and federated access to shared services. Integrations with Datadog and other tools enable comprehensive monitoring and observability.
