The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. LinearB targets engineering managers and vp engineering and leads with cycle-time-metrics and dora-metrics.
Harbor uses custom enterprise pricing, while LinearB starts at $39/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.
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.
