The Verdict
Cloudflare is built for websites and web applications, with a focus on cdn and ddos-protection. Harbor targets enterprise devops and container teams and leads with container-registry and vulnerability-scanning.
Harbor uses custom enterprise pricing, while Cloudflare starts at $20/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, Cloudflare offers broader built-in capabilities (8 features vs 7), while Harbor takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Cloudflare has a slight overall edge — but if completely free and cncf graduated project matters most to you, Harbor may still be the right call.
