Development Containers is described as 'A development container (or dev container for short) allows you to use a container as a full-featured development environment. It can be used to run an application, to separate tools, libraries, or runtimes needed for working with a codebase, and to aid in continuous integration' and is an app. There are six alternatives to Development Containers for a variety of platforms, including Linux, Mac, Windows, Docker and Flathub apps. The best Development Containers alternative is DevPod, which is both free and Open Source. Other great apps like Development Containers are Flox.dev, Jetify Devbox, devenv and OpenBoot.
DevPod is infrastructure-independent and client-only, which makes it incredibly easy to get started with. Codespaces but open-source, client-only and unopinionated. Works with any infra, any programming language, any IDE, etc.
Devbox is a command-line tool that lets you easily create reproducible, reliable dev environments. You start by defining the list of packages required by your development environment, and devbox uses that definition to create an isolated environment just for your application.
Jetify (formerly jetpack.io) is a Nix-based service for deploying applications. DevBox provides a way to use Nix to generate a development environment. Jetify’s VS Code extension allows you to quickly take advantage of DevBox in any Dev Container Spec supporting tool or service.
Apx is the default package manager in Vanilla OS. It is a wrapper around multiple package managers to install packages and run commands inside a managed container.

DevPod is a client-only tool to create reproducible developer environments based on a devcontainer.json on any backend. Each developer environment runs in a container and is specified through a devcontainer.json. Through DevPod providers these environments can be created on any backend, such as the local computer, a Kubernetes cluster, any reachable remote machine or in a VM in the cloud.
