Spacelift

Spacelift provides a sophisticated infrastructure automation platform that brings CI/CD best practices to infrastructure as code with support for Terraform, OpenTofu, Pulumi, CloudFormation, Ansible, and Kubernetes. It manages the full lifecycle of infrastructure changes including planning, approval, execution, and drift remediation. Its AI-powered features analyze plan outputs to flag risky changes, detect configuration drift from desired state, and provide intelligent recommendations for resource management at scale.

Enterprise teams benefit from granular policy-as-code enforcement using Open Policy Agent (OPA), which can block non-compliant changes before they reach production. Spacelift provides approval workflows with Slack and Teams integration, comprehensive audit logging for compliance, SSO via SAML and OIDC, and SCIM-based user provisioning. It supports self-hosted runners for organizations that need infrastructure operations to execute within their own network boundaries, and VCS integration covers GitHub, GitLab, Bitbucket, and Azure DevOps.

Spacelift is designed for platform engineering teams and infrastructure teams managing dozens to thousands of IaC stacks across multi-cloud environments. Its differentiator versus general-purpose CI/CD tools is purpose-built IaC orchestration -- features like state management, workspace dependencies, resource-level drift detection, and context-aware plan policies are native capabilities rather than bolt-on scripts. This specialization means teams spend less time building and maintaining custom IaC pipelines and more time on actual infrastructure design and reliability.
