About Docker Hub

Docker Hub is the container image registry and library operated by Docker. Developers use it to find, share and distribute images, and the same service lets them build, push and pull images from their own workflows.

The library emphasizes trusted content, with Docker Official Images, Docker Hardened Images, Verified Publisher content and Sponsored open-source projects, and images are browsable by categories such as databases, languages and frameworks, networking, security and machine learning. A generative AI section lists AI models and MCP servers, and the homepage promotes Docker Sandboxes, isolated microVMs where agents run with controlled tools, files, network rules and credentials. Reusable Sandbox Kits are published there as well.

Docker Hub is a hosted proprietary service. You can sign up from the site, and plan and pricing details are on Docker's pricing page.
