The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Rocket.Chat targets security conscious organizations and government and leads with channels and direct-messaging.
Harbor uses custom enterprise pricing, while Rocket.Chat starts at $4/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 Rocket.Chat takes a more focused approach — which can mean a simpler, faster onboarding experience.
