Spacelift

Spacelift is an infrastructure-as-code management platform that provides orchestration, policy enforcement, and collaboration features for teams managing cloud infrastructure at scale. It supports Terraform, OpenTofu, Pulumi, CloudFormation, Ansible, and Kubernetes, making it one of the most versatile IaC management solutions available. The platform serves as a centralized control plane for infrastructure changes, replacing ad-hoc CI/CD pipelines with purpose-built workflows for IaC. One of Spacelift's standout capabilities is its drift detection engine, which continuously monitors deployed infrastructure and alerts teams when resources have been modified outside of the IaC workflow, whether through manual console changes or other automation tools. When drift is detected, Spacelift can automatically reconcile the state, ensuring the deployed infrastructure always matches its declared configuration. Policy enforcement through Open Policy Agent (OPA) allows platform teams to define guardrails that prevent dangerous changes. For example, policies can block the deletion of production databases, require tagging on all resources, or restrict instance types to approved configurations. This approach shifts governance left, catching compliance violations before they are applied rather than auditing after the fact. SpaceLift's AI-assisted features analyze proposed infrastructure changes to surface potential issues and explain the impact of modifications in plain language. The approval workflow system supports multi-stage reviews where different stakeholders can approve changes based on their scope and risk level. Plan previews let teams see exactly what will change before applying, with clear diffs and dependency visualization. The platform is best suited for DevOps and platform engineering teams in mid-size to large organizations that manage complex multi-cloud or multi-tool infrastructure environments. Teams standardizing on a single IaC tool may find simpler solutions sufficient, but organizations juggling Terraform alongside Pulumi or CloudFormation will appreciate Spacelift's unified management layer. SpaceLift is a paid product with pricing starting at approximately $40 per month. There is no free tier, though the company offers trial periods for evaluation. Self-hosted deployment is available for enterprises with strict data residency or air-gapped environment requirements. Pricing scales based on the number of managed infrastructure stacks and concurrent runs.
