Top 10 Container Tools
Container tools build, run, and manage OCI-compliant containers on developer workstations and CI systems. They provide the runtime and toolchain for packaging applications into portable images.
Why this category matters
Containers guarantee that software runs the same way in every environment by bundling application code with its dependencies. Container tools make building and running these environments straightforward.
When to use these tools
Adopt container tools when you want consistent environments across development, CI, and production. They are essential prerequisites for Kubernetes adoption.

Container Tools — FAQ
Is Podman a replacement for Docker?
Podman is a daemonless, rootless alternative to Docker that is OCI-compatible. It can run most Docker commands as a drop-in replacement and is preferred in security-sensitive environments.
What is the difference between containerd and Docker?
containerd is a low-level container runtime that Docker uses internally. It is also used directly by Kubernetes. Docker provides a higher-level developer experience on top of containerd.
What tools can I use on macOS instead of Docker Desktop?
Colima, Lima, Rancher Desktop, OrbStack, and Finch are popular free or open-source alternatives to Docker Desktop on macOS.
