The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Portainer targets devops engineers and system admins and leads with container-management and stack-deployment.
Harbor uses custom enterprise pricing, while Portainer starts at $12/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 Portainer takes a more focused approach — which can mean a simpler, faster onboarding experience.
This is a genuinely close comparison. If you can, sign up for both free trials (where available) and run a one-week test with your actual team tasks before deciding.
