Open-source alternatives to Magnet

I want to pick an open-source replacement for Magnet. 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. - Rectangle: Rectangle is a free app for Mac computers that arranges open windows by snapping them to the edges of the screen or to keyboard shortcuts. It is for everyday Mac users who want their windows organized without manual resizing. [Easy setup; Mac; replaces fully; MIT; https://github.com/rxhanson/Rectangle] - PowerToys PowerRename: PowerToys PowerRename is one of over 30 free utilities bundled in Microsoft PowerToys, a set of add-ons that customize Windows. It is for Windows users who want to rename many files at once. [Easy setup; Windows; replaces fully; MIT; https://github.com/microsoft/PowerToys] - GlazeWM: GlazeWM is a free program for Windows that automatically arranges open windows into neat tiles, controlled mostly with keyboard shortcuts. It is aimed at people who want to organize their screen quickly without using the mouse. [Easy setup (It has an installer for Windows that you run like any other program.); Windows; replaces partly; GPL-3.0; https://github.com/glzr-io/glazewm] - AeroSpace: AeroSpace is a free tool for Mac computers that automatically arranges open windows into tiles, controlled mainly with the keyboard. It is aimed at advanced users and programmers who want to manage windows without using the mouse. [Easy setup; Mac; replaces partly; MIT; https://github.com/nikitabobko/AeroSpace] 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/window-snapping.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.
