The Verdict
Docker is built for developers and devops engineers, with a focus on containerization and docker-hub. GitLab targets enterprise and devops teams and leads with source-control and ci-cd.
On pricing, Docker is the clear winner for budget-conscious users — starting at $5/mo compared to $29/mo for GitLab. That $24/mo difference adds up quickly for growing teams.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Docker offers broader built-in capabilities (8 features vs 7), while GitLab takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Docker has a slight overall edge — but if all-in-one devops — no tool sprawl matters most to you, GitLab may still be the right call.
