It's a split decision.
Spacelift is an infrastructure orchestration platform; Terraform is an IaC tool and CLI, with team workflows available through HCP Terraform. Choose Spacelift when you need centralized workflows across Terraform and other IaC systems, OPA policy guardrails, drift visibility, and Day 2 automation. Choose Terraform when you want to define and manage infrastructure with Terraform configuration and CLI workflows, or need HCP Terraform collaboration. They overlap, but operate at different layers, so teams can use Terraform through Spacelift rather than replace it.

02Pricing at real usage
Spacelift Free costs $0 and includes two users and one API key. Starter is listed at $399 per month with annual billing, for up to 10 users and two public workers. Business includes unlimited users; Enterprise starts at five workers. The pricing page does not list prices for Business or Enterprise.
Terraform's HCP Free tier costs $0 and includes unlimited users, up to 500 managed resources, one concurrent run, and $500 in HCP credit. Paid HCP tiers scale with managed resources: Essentials is $0.00013 per resource per hour, Standard is $0.00064, and Premium is $0.00135. The listed monthly equivalents are $0.10, $0.47, and $0.99 per resource. Paid usage can exceed trial credits or commitments; the pricing page lists no annual rates. Compare expected resource-hours with Spacelift's subscription and worker requirements before estimating total cost.
03API, SDKs and integration
Spacelift is presented as a web orchestration platform. It supports Terraform, OpenTofu, CloudFormation, Pulumi, Kubernetes, and Ansible, and connects to cloud accounts and MCP servers. Its homepage describes stacks and dependencies, OPA-based policies, Spaces, Contexts, and RBAC. It does not specify API endpoint conventions or language SDKs.
Terraform's developer workflow centers on its CLI and configuration language. Its documentation navigation includes Terraform CLI, configuration language, provider use, policy, plugin development, and registry publishing. The Terraform Registry and tutorials for AWS, Azure, Google Cloud, Oracle Cloud, and Docker give teams paths into its provider ecosystem. The homepage also lists GitHub Actions, Vercel, HCP Terraform, and Terraform MCP Server in tutorials or documentation. Neither product page identifies language SDKs or API contracts, so confirm API access and client support with the vendor if those are integration requirements. Architecturally, Spacelift coordinates runs across supported tools; Terraform provides the configuration and provisioning workflow.
04Open source, self-hosting and lock-in
Neither product page identifies an open-source license, and data-export formats are not published. Spacelift says it is self-hostable; ask the vendor about deployment requirements, upgrades, and support terms before making that a control-plane requirement. Terraform's product pages identify a CLI and HCP Terraform collaboration workflows, but do not establish a self-hosting model. Confirm deployment choices with the vendor.
The products operate at different layers, so migration depends on what you are replacing. Spacelift supports Terraform as well as other IaC systems, which lets teams use it to orchestrate Terraform workflows rather than rewrite their configurations. Moving orchestration still means reviewing policies, access controls, automation, run history, and state handling. Ask both vendors how to export relevant data and which formats are supported before switching platforms.
Questions people ask
Is Spacelift a replacement for Terraform?
Usually no. Spacelift is an orchestration layer that supports Terraform alongside OpenTofu, CloudFormation, Pulumi, Kubernetes, and Ansible. Terraform is the IaC tool and CLI. Teams can keep Terraform configurations and add Spacelift for policy, approvals, drift visibility, and Day 2 automation.
Can Spacelift work with other IaC tools?
Yes. Spacelift lists support for OpenTofu, CloudFormation, Pulumi, Kubernetes, and Ansible in addition to Terraform. It also supports cloud accounts and MCP servers. Check the vendor's integration documentation for the workflow details and requirements relevant to your stack.
How do Spacelift and Terraform pricing compare?
Spacelift uses subscriptions, with Starter listed at $399 per month on annual billing; Business and Enterprise prices are not published. HCP Terraform charges for paid tiers by managed resource and hour, starting at $0.00013 per resource-hour on Essentials. Compare your user, worker, and resource needs.
Which is better for a small team?
Terraform's free HCP tier allows unlimited users but caps usage at 500 managed resources and one concurrent run. Spacelift Free allows two users and one API key. Pick based on whether your immediate need is Terraform provisioning or broader orchestration and governance.
