Open-source alternatives to 4K Video Downloader

I want to pick an open-source replacement for 4K Video Downloader. 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. - cobalt: cobalt is a free tool for saving videos, music and images from websites to your own device. It is aimed at everyday people who want a simple way to keep media they like, with no ads or paywalls. [Easy setup; In your browser; replaces fully; AGPL-3.0; https://github.com/imputnet/cobalt] - Seal: Seal is an Android phone app that downloads videos and audio from many websites so you can keep them on your device.

It is for people who want to keep and browse their own YouTube archive on their own server. [Advanced setup; runs on a server you set up; replaces partly; GPL-3.0; https://github.com/tubearchivist/tubearchivist] 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/media-downloaders.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.
