It's a split decision.
Docker is the developer-side container and agent runtime: use it for local container workflows, agent sandboxes, hardened images, and moving work to cloud sandboxes. Replicated is the delivery control plane for vendors shipping commercial software into customer-managed environments, including air-gapped installs. Choose by deployment boundary: Docker helps build and run your stack; Replicated helps release, license, install, and support your product inside customers’ infrastructure.

Docker Choose Docker if
- Choose Docker if you need local container development and agent sandboxes.
- Choose Docker if your stack already uses images, registries, and CI.
- Choose Docker if you want a free individual plan or hardened images.
Replicated Choose Replicated if
- Choose Replicated if you ship commercial software into customer-managed environments.
- Choose Replicated if you need air-gap installs and customer licensing.
- Choose Replicated if compatibility testing and release workflows are priorities.
02Pricing at real usage
Docker Personal is free for one user and includes one private Docker Hub repo and 100 pulls per hour. DHI Community is also free per developer. Docker Pro costs $11 per user monthly or $9 billed annually; Team costs $16 or $15, and Business costs $24 either way. Docker’s pricing page lists additional Testcontainers Cloud minutes at $3 per 100 minutes, or $4 per 100 on demand. DHI Select starts at $5,000 per repo.
Replicated lists a free plan, but does not specify its scope. Compatibility Matrix starts at $500 monthly; Builders is $2,000 and Business is $3,000 monthly. Builders and Business also charge per license, and Compatibility Matrix charges for additional clusters; those fees are not published. Compare the license and cluster charges with your expected installs and test environments before budgeting.
03API, SDKs and integration
Docker’s homepage positions its tools alongside existing images, registries, and CI, and names Claude, MCP, and OCI. It shows the docker agent run command for starting an agent. Docker Desktop brings container development into the local workflow, while Sandboxes can run locally or in the cloud. The homepage does not describe a public API or SDK, or name supported SDK languages.
Replicated describes a product lifecycle for developing, testing, licensing, releasing, installing, reporting on, and supporting customer-managed software. Its homepage says Compatibility Matrix integrates with CI and that the platform provides an API. It also links to product documentation. Replicated does not identify API protocols, SDKs, or supported programming languages there. Its integration emphasis is release and deployment operations: compatibility testing, license entitlements, air-gap installs, customer segments, and support bundles. These are different integration surfaces, so check API details and workflow fit against your existing CI and release process.
04Open source, self-hosting and lock-in
Docker’s DHI Community offer includes an open-source image catalog under Apache 2.0. That license claim applies to the catalog, not necessarily Docker’s full platform. Docker describes local development and cloud sandboxes, and says its platform is OCI-compliant and platform-independent. Those details point to working with existing container infrastructure, but do not establish that Docker’s governance services can be self-hosted.
Replicated is built to distribute software that runs in customers’ environments, including air-gapped servers, bare metal, VMs, and VPCs. That is customer-managed deployment support, not evidence that Replicated’s own service is self-hostable. Neither vendor describes data-export formats or a migration path on its homepage. Before committing, ask about exporting audit, licensing, compatibility, and instance data, and test how easily your release process can move to another tool.
Questions people ask
Are there other containers than Docker?
Docker says its platform is OCI-compliant and platform-independent, and that teams can use existing images and registries. That points to an ecosystem broader than one vendor’s tooling. The homepage does not compare specific alternatives, so check OCI compatibility and required runtime features when evaluating another container stack.
Can I learn Docker in 2 days?
Docker does not promise a learning timeline. Its homepage describes container development through Docker Desktop and agent runs through a command such as docker agent run. How much you can learn in two days depends on your starting point and whether you need basic container workflows or governance, sandbox, and image-security features.
Is Docker still relevant in 2026?
Docker’s 2026 product offering covers container development, agent sandboxes, AI governance, and hardened images. Its homepage also says the platform is OCI-compliant and works with existing images, registries, and CI. That makes it relevant to teams using those workflows; it does not make Docker a substitute for Replicated’s customer-software distribution lifecycle.
How is Docker different from GitHub?
Docker describes tools for building and running containers, plus sandboxing and governance for agents. GitHub is not a direct comparison in Docker’s product description. For a stack decision, compare the specific jobs: Docker’s container and runtime features versus the source-control and collaboration capabilities your team needs.
