It's a split decision.
Choose Docker if you need tools to build and run containerized apps, develop locally, or isolate AI agents in local or cloud sandboxes. Choose Docker Hub if your main job is to push images to a hosted registry, manage team access, and connect builds or webhooks to a development pipeline. They are not direct substitutes: Docker describes support for existing registries, while Hub is one place to store and share images. Their listed Personal, Pro, Team, and Business prices overlap.

Docker Choose Docker if
- Choose Docker if you need container development tools across Mac, Windows, or Linux.
- Choose Docker if agents need local or cloud microVM sandboxes.
- Choose Docker if hardened images, MCP policy, or governance are part of your stack.
Docker Hub Choose Docker Hub if
- Choose Docker Hub if you need a hosted place to push and share images.
- Choose Docker Hub if teammates need repository-level access.
- Choose Docker Hub if automated builds and webhooks fit your pipeline.
02Pricing at real usage
Both products list Docker Personal at $0, Pro at $11 per user monthly or $9 billed annually, Team at $16 monthly or $15 annually, and Business at $24 under either billing option. Personal includes one private Hub repository and 100 Docker Hub pulls per hour; Pro includes unlimited pull rate. Team supports up to 100 users, while Business has no user cap. Docker's plans also list Docker Scout and Testcontainers Cloud allowances: 100, 500, or 1,500 runtime minutes monthly on Pro, Team, or Business. Extra Testcontainers Cloud minutes cost $3 per 100 minutes, or $4 per 100 on demand. Docker also lists DHI Community free, DHI Select starting at $5,000 per repository, and custom-priced DHI Enterprise. Those hardened-image offers are separate from Hub's registry plans.
03API, SDKs and integration
Docker's homepage positions the platform around existing images, registries, and CI rather than a required replacement stack. It names Claude, MCP, and OCI compliance, and shows a docker agent run command for starting an agent. Docker Desktop supports the container development loop; Docker also describes moving agent work from a laptop to Cloud Sandboxes. The homepage does not name programming-language SDKs or describe a public API, so confirm those interfaces in the documentation before choosing an integration path.
Docker Hub is a hosted image registry. Its homepage lists repository access for teams, automated builds, and webhooks for development-pipeline workflows, but names no specific third-party services or language SDKs. It features Docker Official Images, Docker Hardened Images, Verified Publishers, and sponsored open-source projects. Hub's homepage does not describe a public API or CLI workflow. In both cases, check the relevant product documentation for implementation details rather than assuming a particular SDK or protocol.
04Open source, self-hosting and lock-in
Docker's developer facts and Docker Hub's homepage do not state that either product is open source or identify a license for the products themselves. Docker does say its platform is OCI-compliant and platform-independent, and that teams can keep using existing images, registries, and CI. That may help fit Docker into a stack built on those tools, but it is not a published data-export or migration procedure.
Docker Hub is described as a hosted registry, not a self-hosted server. Docker describes local container development and local agent sandboxes, which are not the same as self-hosting Docker Hub. Neither product page publishes a registry export or migration procedure. Before committing production images to Hub, ask Docker about bulk export, repository metadata, and migration support, and confirm which OCI-compatible registries your deployment can use.
Questions people ask
What is the best container registry?
Docker Hub is a hosted registry where teams can push images, share them with teammates or the community, and manage repository access. Its catalog includes Docker Official Images, Docker Hardened Images, and Verified Publishers. Whether it fits depends on your pull rate, private-repository needs, and how you manage registry migration.
Is a Dockerfile a .txt file?
Docker's homepage describes tools for building and running containerized apps, but it does not specify a Dockerfile's filename or extension. Check Docker's build documentation for the filename expected by your build workflow rather than assuming a .txt extension.
What can I use instead of Docker?
Docker's homepage says the platform is OCI-compliant and platform-independent, and that teams can use existing images, registries, and CI. It does not name alternative products. If you are comparing options, check that they support the image formats, registry workflow, and agent isolation your stack requires.
What is the difference between Docker images and Docker containers?
Docker Hub is for pushing and sharing images. Docker's platform is for building, shipping, and running containerized apps. The product pages do not define the technical distinction between an image and a running container, so consult Docker's technical documentation for that terminology.
