Spacelift is policy-as-code CI/CD for IaC with AI embedded in the run output.
Spacelift runs Terraform, OpenTofu, Pulumi, Ansible, and CloudFormation under OPA guardrails with drift detection, a private module registry, and full audit trails. Spacelift Intelligence (March 2026) sits inside the run context and explains plan summaries, policy violations, and remediation paths inline. The AI is in the run, not a side chatbot.
Who it's for. Platform teams of 10 to 50 engineers needing auditability, multi-stack IaC support, and guardrails. Scenario: a developer opens a PR that creates a public S3 bucket, Spacelift runs the plan, OPA blocks it under no-public-s3-buckets, and Intelligence explains: the bucket on line 23 has acl public-read, change to private or attach a bucket policy.
Tradeoffs. IaC-focused; it does not deploy containers, Lambdas, or app code. Intelligence is new and evolving fast. Compared to env0, Spacelift has broader IaC language coverage (Ansible, CloudFormation) but env0's AI Code Generator is deeper. Enterprise pricing is sales-only. Free tier covers individual use.
Compare: env0, Terraform Cloud, Scalr, Terramate
