Spacelift is completely free with 7 features included. No paid tiers offered, making it perfect for budget-conscious users.
Terraform Cloud charges per managed resource (the RUM model), so your bill grows linearly with your infrastructure size. Spacelift charges per concurrent worker, so your bill scales with how many simultaneous runs you need. For large infrastructure estates (5,000+ resources), Spacelift can be 3-5x cheaper. For small setups, the difference is less significant.
Yes. Spacelift added first-class OpenTofu support and actively positions itself as the leading orchestration platform for OpenTofu. If you're migrating away from HashiCorp's BSL-licensed Terraform, Spacelift is one of the smoothest paths.
If your infrastructure state contains sensitive data (database credentials, network configurations, etc.) and your security team won't allow it to transit public infrastructure, yes. Public workers run in Spacelift's shared pool with container isolation. Private workers run in your own VPC. Most startups are fine with public workers; regulated industries typically need private.
Enterprise plan only. Spacelift can be deployed entirely within your infrastructure. This is important for air-gapped environments or organizations with strict data sovereignty requirements.
Spacelift raised $51M to expand the platform, particularly around multi-IaC support and enterprise features. The funding signals strong market confidence, but it also means the company needs to grow revenue — watch for pricing changes as they scale.
It's completely free — no credit card required.
