Open-source alternatives to Docker Desktop

I want to pick an open-source replacement for Docker Desktop. Below is a list from Open Source Everything (CC BY-SA 4.0), in the order its website shows it. The order is a starting point, not a verdict. - k3s: K3s is a lightweight version of Kubernetes, a system for running and managing containerized applications across one or more computers, packaged as a single small program that is easier to install. It is aimed at people running clusters on small or limited hardware, at the network edge, in testing and development, and at anyone who finds full Kubernetes too complex to set up. [Advanced setup; Linux; replaces fully; Apache-2.0; https://github.com/k3s-io/k3s] - Headlamp: Headlamp is a free web-based control panel for viewing and managing Kubernetes, the system that runs many apps across groups of computers. It is for people and teams who operate Kubernetes clusters and want a visual way to work with them. [Easy setup (It has a desktop app for Windows, Mac and Linux.); Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/kubernetes-sigs/headlamp] - Podman: The material provided is the source code for the podman.io website, the home page for the Podman project. It does not describe what Podman itself does, so the website's purpose is the only thing confirmed here. [Advanced setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/podman-container-tools/podman] - Kubernetes: Kubernetes is a free, open system that manages software packaged in containers across many computers, handling how apps are started, kept running, and scaled. It is for programmers and IT teams who run applications on server clusters. [Advanced setup; runs on a server you set up; replaces partly; Apache-2.0; https://github.com/kubernetes/kubernetes] - K9s: K9s is a text-based screen tool that lets you watch and manage applications running on Kubernetes clusters, the systems used to run containers. It is for programmers and IT staff who work with Kubernetes. [Advanced setup; Windows · Mac · Linux · Android; replaces partly; Apache-2.0; https://github.com/derailed/k9s] Setup rating: "Easy setup" means you can install it like a normal app, use it in a browser. "Advanced setup" means you must run it on your own server or use the command line, or it is a tool for developers. Full details: https://opensourceeverything.org/data/groups/containers.json Before recommending anything, ask me these three questions (one at a time, in plain words): 1) Which device or devices will I use it on (Windows, Mac, Linux, Android, iPhone)? 2) How comfortable am I with technical setup: only installing apps from a store, happy to follow a step-by-step guide, or comfortable with servers and the command line? 3) What is my budget: free only, or willing to pay for hosting or support? Then recommend one to three projects from this list only, and for each say why, using how fully it replaces the app, its setup rating, and the devices it runs on. If nothing on the list fits me, say so plainly instead of stretching.

Read the list of open-source projects at https://opensourceeverything.org/data/groups/containers.json. Compare it with my project or idea below. Tell me which projects overlap, what I could reuse instead of rewriting, and what mine does that none of them do. My project or idea:
