Docker is described as 'Open-source engine that automates the deployment of any application as a lightweight, portable, self-sufficient container that will run virtually anywhere' and is a very popular Virtualization tool in the system & hardware category. There are more than 25 alternatives to Docker for a variety of platforms, including Linux, Mac, Windows, Self-Hosted and BSD apps. The best Docker alternative is Podman, which is both free and Open Source. Other great apps like Docker are Linux Containers (LXC), Distrobox, OrbStack and BitNami Application Stacks.
Podman is a daemon-less container runtime for managing containers, pods, and container images. It is intended as a counterpart to CRI-O, to provide low-level debugging not available through the CRI interface used by Kubernetes.
Drop-in replacement without the license restrictions of Docker
Containers which offer an environment as close as possible as the one you'd get from a VM but without the overhead that comes with running a separate kernel and simulating all the hardware.
Use any Linux distribution inside your terminal. Enable both backward and forward compatibility with software and freedom to use whatever distribution you’re more comfortable with. Distrobox uses podman or docker to create containers using the Linux distribution of your choice.
OrbStack is an alternative to Docker Desktop for macOS, designed to offer improved performance for Docker and virtual machines on Linux running on Mac computers. It addresses performance issues that have been experienced in the past, particularly on models with Apple Silicon.
BitNami Stacks make it incredibly easy to deploy your favorite open source software. BitNami Stacks include an open source application and all of the other software necessary to run it, such as Apache, MySQL, PHP or Ruby.
rkt is the next-generation container manager for Linux clusters. Designed for security, simplicity, and composability within modern cluster architectures, rkt discovers, verifies, fetches, and executes application containers with pluggable isolation.
An industry-standard container runtime with an emphasis on simplicity, robustness and portability
ServBay is a specially crafted local dev env platform made for web developers. It integrates all the essential components for daily development, including programming languages, SQL/NoSQL databases, web servers, DNS services, email services, SSL certificate, and AI/LLM features.
CRI-O is an implementation of the Kubernetes CRI (Container Runtime Interface) to enable using OCI (Open Container Initiative) compatible runtimes. It is a lightweight alternative to using Docker as the runtime for kubernetes.
It is supported by Red Hat
OpenVZ is container-based virtualization for Linux.
OpenVZ creates multiple secure, isolated Linux containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict.
