Open-source alternatives to LaunchBar

I want to pick an open-source replacement for LaunchBar. 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. - Flow Launcher: Flow Launcher is a free tool for Windows computers that lets you search for and open apps, files, and web pages by typing into a small search box. It is for Windows users who want to get to things quickly from the keyboard. [Easy setup; Windows; replaces fully; MIT; https://github.com/Flow-Launcher/Flow.Launcher] - rofi: Rofi is a keyboard-driven tool that lets you switch between open windows, launch applications, and pick items from a text list. It is aimed at people who prefer working from the keyboard on Linux and BSD computers. [Easy setup; Linux; replaces fully; MIT; https://github.com/davatorium/rofi] - 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 partly; MIT; https://github.com/microsoft/PowerToys] - Ulauncher: Ulauncher is a free program for Linux computers that lets you open apps, files and commands quickly by typing into a search box. It is for everyday Linux desktop users who want a fast alternative to clicking through menus. [Easy setup; Linux; replaces partly; GPL-3.0-or-later; https://github.com/Ulauncher/Ulauncher] 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/launchers.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.
