The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Heroku targets startups and prototyping and leads with git-deploy and managed-postgres.
Harbor uses custom enterprise pricing, while Heroku starts at $5/mo — a tangible advantage for teams with a fixed budget.
Harbor has a free plan, which gives it a meaningful edge for individuals and small teams exploring their options. Heroku requires a paid subscription from day one.
Bottom line: Harbor has a slight overall edge — but if simplest deployment experience (git push to deploy) matters most to you, Heroku may still be the right call.
