The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Spacelift targets platform teams and devops engineers and leads with iac-orchestration and policy-engine.
Harbor uses custom enterprise pricing, while Spacelift starts at $35/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Harbor offers broader built-in capabilities (7 features vs 6), while Spacelift takes a more focused approach — which can mean a simpler, faster onboarding experience.
