It's a split decision.
Docker is a container development platform that also offers agent sandboxes, governance, and hardened images. Nexus Repository is an artifact repository for storing and managing software components and models, available in cloud and self-hosted editions. Choose Docker if your priority is container workflows, local development, or agent isolation. Choose Nexus Repository if you need a system of record for packages, integrations with build pipelines, or a self-hosted repository. Their free offerings serve different needs, so compare the specific workload and usage limits.

02Pricing at real usage
Docker Personal is free and includes one user, one Docker Scout-enabled repository, 100 Docker Hub pulls per hour, and one private repository. Pro costs $11 per user monthly or $9 per user per month billed annually; Team costs $16 or $15, and Business costs $24 either way. DHI Community is free; DHI Select starts at $5,000 per repository, while Enterprise pricing is custom.
Nexus Repository Community Edition is a free self-hosted download. Cloud Pro costs $1,950 per year plus consumption and includes 25 GB; additional usage costs $1.10 per GB per month for the first 1,000 GB, then $0.90 for 1,001–2,500 GB. Cloud Pro+ and Enterprise have custom pricing. Self-Hosted Pro costs $7,500 annually and specifies 50,000 components and 15 million monthly requests. Cloud costs can grow with storage consumption; Docker’s paid plans scale mainly by seats, with Testcontainers minutes and DHI offerings billed separately.
03API, SDKs and integration
Docker describes a stack that works with existing images, registries, and CI, rather than requiring a new ecosystem. Its homepage also names Claude, MCP, and OCI compliance. Docker Desktop brings containers into the development loop; homepage examples show the docker agent run and sbx run commands for agent workflows. Docker describes local sandboxes and a move to Cloud Sandboxes, but does not specify a language SDK or API protocol on the homepage.
Nexus Repository lists support for Maven, Hugging Face, PyPI, npm, and NuGet, plus Jenkins, GitHub Actions, and GitLab CI/CD integrations. Paid editions include an Audit Log API, but the product pages do not specify its protocol or client SDKs. Neither vendor publishes language-specific SDK details on these product pages. For implementation planning, verify the API contract and authentication details for Nexus, and how Docker’s sandbox controls fit your existing CI and registry setup.
04Open source, self-hosting and lock-in
Docker’s DHI Community offering includes open-source images under Apache 2.0. That does not establish an open-source licence for Docker’s broader platform. Nexus Repository offers a free Community Edition download and paid self-hosted editions, but Sonatype does not publish the Community Edition licence on its pricing page. Confirm the licence terms for your intended use before adopting it.
Nexus explicitly supports self-hosted deployments; Docker describes local development and cloud sandboxes, not a self-hosted repository service. Docker says its stack is OCI-compliant and works with existing images, registries, and CI, which can help preserve familiar container workflows. Nexus lists multiple package ecosystems and CI integrations. Neither vendor publishes a data-export path on these pages. Before committing, ask how to export stored artifacts, metadata, audit records, and configuration, and estimate migration work for your repository formats and pipeline references.
Questions people ask
Are Docker and Nexus Repository alternatives?
Not usually. Docker provides container development tools and agent security features. Nexus Repository stores and manages software artifacts and models. They can serve different roles in the same build stack: Docker for container workflows and Nexus Repository for component storage and governance.
Can Nexus Repository be self-hosted?
Yes. Sonatype offers a free Self-Hosted Community Edition and paid self-hosted Pro, Pro+, and Enterprise editions. Self-Hosted Pro is listed at $7,500 per year and includes 50,000 components and 15 million monthly requests.
Does Docker include a free plan?
Yes. Docker Personal is free and includes one user, one Docker Scout-enabled repository, 100 Docker Hub pulls per hour, and one private Docker Hub repository. Docker also lists DHI Community as a free option for hardened, minimal images.
How much does Nexus Repository Cloud cost?
Cloud Pro costs $1,950 per year plus consumption and includes 25 GB. Additional consumption is priced by monthly gigabytes, with listed rates of $1.10 per GB for the first 1,000 GB and $0.90 for 1,001–2,500 GB. Pro+ and Enterprise require custom pricing.
