If you’ve been managing your infrastructure with local CLI commands and a shared S3 bucket for state, you know the pain of state locking and the ‘who ran apply last?’ Slack messages. When you move to a managed platform, the big question usually becomes: should i use terraform cloud or spacelift?
I’ve spent the last year managing several multi-cloud environments, and I’ve found that while both tools solve the basic problem of remote state and execution, they approach the ‘orchestration’ part of Infrastructure as Code (IaC) from completely different philosophies. One is the ‘official’ path; the other is the ‘power-user’ path.
Terraform Cloud: The Path of Least Resistance
Terraform Cloud (TFC) is developed by HashiCorp. If you want the most seamless integration with the Terraform binary itself, this is where you start. In my experience, TFC is fantastic for teams that want to get up and running in ten minutes without fighting the tooling.
The Strengths
- Zero-Friction Setup: Since it’s the native product, the VCS integration is nearly instant.
- Private Module Registry: I’ve found their registry to be one of the cleanest ways to share standardized modules across a large organization.
- Sentinel: Their proprietary policy-as-code framework is powerful, though it has a learning curve.
The Trade-offs
The biggest limitation I’ve encountered with TFC is its relative rigidity. It follows a very specific workflow. If you need highly complex trigger logic—like ‘only run this plan if a specific tag in a different workspace changed’—you’ll find yourself hitting a wall. Additionally, for those looking into IaC drift detection tools review, TFC’s native capabilities are improving but often feel more reactive than proactive.
Spacelift: The Power User’s Orchestrator
Spacelift doesn’t just want to run your Terraform; it wants to orchestrate your entire cloud lifecycle. It treats IaC as a first-class citizen of the CI/CD pipeline rather than just a wrapper around terraform apply.
The Strengths
- OPA (Open Policy Agent): Unlike Sentinel, Spacelift uses OPA. Since OPA is an industry standard, I can use the same Rego policies across my Kubernetes cluster and my IaC pipeline.
- Complex Triggering: Their ‘blueprints’ and dependency graphs are a lifesaver. I can trigger a sequence of applies across ten different stacks in a specific order.
- Multi-Tool Support: It handles OpenTofu, Terraform, and Pulumi with equal grace.
The Trade-offs
Spacelift is significantly more complex. If you are a solo developer or a tiny team, the amount of configuration required to get the most out of Spacelift might feel like overkill. For a deeper dive, check out my Spacelift review for enterprise IaC where I break down the policy engine in detail.
Feature Comparison: At a Glance
As shown in the comparison below, the choice usually comes down to whether you value simplicity (TFC) or flexibility (Spacelift).
| Feature | Terraform Cloud | Spacelift |
|---|---|---|
| Policy Language | Sentinel (Proprietary) | OPA/Rego (Open Standard) |
| Trigger Logic | Basic / Linear | Advanced / Dependency Graphs |
| Tool Support | Terraform/OpenTofu | Terraform, OpenTofu, Pulumi, CloudFormation |
| Learning Curve | Low | Medium to High |
| State Management | Excellent | Excellent |
Pricing and Value
Terraform Cloud has a very generous free tier for small teams, which makes it the default choice for startups. However, as you scale into ‘Plus’ or ‘Enterprise’ tiers, the cost can spike quickly based on resources managed.
Spacelift’s pricing is often more predictable for larger enterprises because it focuses on the number of users and the complexity of the orchestration rather than just the number of resources. In my tests, Spacelift often provides more ‘bang for the buck’ once you hit the 50+ developer mark.
The Verdict: Which One Should You Choose?
So, should i use terraform cloud or spacelift? Here is my practical rule of thumb:
Choose Terraform Cloud if…
- You are a small team or a startup that needs to move fast.
- You are exclusively using Terraform and don’t plan to diverge.
- You prefer a managed experience where the platform makes the architectural decisions for you.
Choose Spacelift if…
- You are managing an enterprise-scale environment with hundreds of workspaces.
- You need strict compliance via OPA (Open Policy Agent).
- You use a mix of IaC tools (e.g., some Pulumi, some Terraform).
- You need complex deployment pipelines with cross-stack dependencies.
If you’re still unsure, I recommend starting with TFC for a month. If you find yourself fighting the platform to implement a custom workflow, that is your signal to migrate to Spacelift.
