Docker remains the most widely used containerisation platform among developers. It simplifies the process of building, running and sharing containers by packaging software into isolated environments with their own filesystem.

In this post, I’ll explore 7 alternatives to Docker each offering a unique approach to container creation and deployment.

Is Docker Still the Best Option Today?

By 2025, Docker is no longer the only or necessarily the best option for working with containers. Depending on your needs, a different tool might be a better fit. Alternatives can address specific Docker limitations. It offer better alignment with your infrastructure or eliminate the need to run the Docker daemon entirely. Also you may prefer to use the same container technology across both development and production environments for consistency.

Some of the tools I’ll cover below are full-fledged Docker replacements. Others focus on improving particular aspects of the container workflow. Such as building images or managing runtime environments more efficiently.

Do You Need Docker to Use Containers?

Docker helped bring containers into the mainstream and for many. It’s still synonymous with the concept. However the underlying technology has matured and container standards are now governed by the Open Container Initiative (OCI).

OCI compliant tools, of which Docker is just one. Follow shared specifications that define how container images and runtimes should function. This means images built with Docker are compatible with other OCI based systems and vice versa.

So basically, Docker isn’t required to work with containers. If you switch to another OCI-compatible platform. You will still be able to run existing container images. Including those from popular registries like Docker Hub. I will highlight which alternatives support OCI standards throughout the post.

The Best Docker Alternatives to Consider

Ready to explore your alternatives? Below are 7 container tools worth checking out. While not an big list. These alternatives were picked to showcase the range of use cases and feature sets.

1. Podman

Podman is an open-source, OCI-compliant tool for managing containers and images. It runs on Windows, macOS and Linux. It can serve as a drop-in replacement for Docker.

One of Podman’s key differences is its daemonless architecture there is no background service running. Which can boost performance and reduce security risks.

Podman’s command-line interface is Docker-compatible. So switching is as simple as replacing docker with podman (e.g., podman ps, podman run). It also offers Podman Desktop, a free, open-source alternative to Docker Desktop. Which provides a graphical interface for managing containers without relying solely on the CLI.

2. Rancher Desktop

Rancher Desktop is an open source desktop application for managing containers. Offering a developer friendly experience similar to Docker Desktop without the need for a commercial license.

It includes a full suite of container tools, such as the Docker daemon (optional), containerd, Kubernetes support and command-line utilities like nerdctl and kubectl.

As an all in one platform, Rancher Desktop simplifies container workflows on local machines. Its intuitive interface and built-in dashboards make it easier to manage containers and Kubernetes clusters. You can also quickly switch between Kubernetes versions. Making it ideal for testing upgrades before rolling them out to production.

3. OrbStack

OrbStack is a macOS only alternative to Docker Desktop. Designed to be faster, lighter, and more efficient on Mac.

Tailored specifically for macOS, OrbStack offers seamless integration with the platform and full support for key container features like volume mounts, networking and x86 emulation via Rosetta. It’s a strong choice for developers who work with containers regularly on macOS.

OrbStack supports Docker Compose, Kubernetes, and includes a full-featured CLI alongside its intuitive desktop app. Additional capabilities like file sharing and remote SSH development are built in. While OrbStack is a proprietary tool, it’s free for personal use.

4. Buildah

Buildah is a lightweight tool focused solely on building OCI-compliant container images. It doesn’t handle running containers.

It’s well-suited for image creation within custom tooling or CI pipelines. Thanks to its daemonless architecture and straightforward CLI. You can build images using Dockerfiles or through direct command-line instructions. Giving you flexibility in how you assemble containers.

Buildah also allows you to modify existing images, add files, or run commands and you can mount image filesystems to inspect the build output directly on your host.

5. LXC

Linux Containers (LXC) is a system-level containerisation solution built into Linux. It sits between full virtualisation and lightweight application containers like those used by Docker.

LXC containers behave more like virtual machines. Running a full operating system and supporting multiple workloads inside each container. They persist until manually removed and are managed using familiar VM-like tools and workflows.

Tools like Docker focus on ephemeral, single-process containers designed for short-lived tasks. While ideal for modern micro-services and cloud-native apps, this model can be restrictive for more complex or stateful applications.

LXC is a better fit when you need multi-process support, deeper control over the OS environment or want a more VM-style experience. While it doesn’t natively support OCI containers. It’s possible to convert OCI images into LXC containers using specialised templates.

6. Containerd & Nerdctl

containerd is an OCI-compliant container runtime maintained by the CNCF. It runs as a daemon and is used under the hood by both Docker and Kubernetes. If you’d prefer to move away from Docker. You can install containerd directly and use it as a standalone runtime.

To interact with containerd, you can install Nerdctl, a Docker-compatible CLI. Most Docker commands work the same way—just swap docker with nerdctl (e.g., nerdctl build instead of docker build). Nerdctl also supports Docker Compose commands. Making it easy to adapt existing workflows.

Although setup is a bit more involved than simply installing Docker. This combination offers greater flexibility and control over your container environment. It also gives you early access to new containerd features before they appear in Docker. Plus, you’re free to replace either component as your needs evolve.

7. Runc

runc is a lightweight OCI-compliant container runtime that provides the core functionality for launching containers. It includes a simple CLI for starting containers directly on your host.

While typically used as a low-level component within higher-level tools like containerd. Runc can also be used on its own for advanced or custom setups. It abstracts away the complexities of Linux containerisation such as cgroups, namespaces and chroots—making it easier to build tailored container workflows without touching kernel internals.

If you are building your own container tooling or want maximum control over the runtime layer, runc offers a minimal and powerful foundation.
