Spacelift is a specialized CI/CD platform built specifically for infrastructure as code workflows. While general-purpose CI/CD tools can run IaC, Spacelift understands the nuances of infrastructure management — state locking, plan previews, drift detection, and policy enforcement — and bakes them into the platform.
The platform supports Terraform, OpenTofu, Pulumi, CloudFormation, Kubernetes, and Ansible. It provides a visual dashboard for managing stacks, reviewing plan outputs before applying changes, and tracking infrastructure drift. Teams can set up approval workflows, OPA (Open Policy Agent) policies, and cost estimation before any changes go live.
Spacelift’s worker pools allow organizations to run IaC operations within their own networks, keeping credentials and state files secure. The platform also supports dependencies between stacks, so changes in shared infrastructure can automatically trigger downstream updates.
Founded in 2020 and headquartered in Mountain View, Spacelift has attracted customers frustrated with the limitations of Terraform Cloud/Enterprise or the complexity of building custom IaC pipelines. The company has raised funding from Bain Capital Ventures and other investors, growing rapidly as the IaC management space expands.
