Open-source alternatives to Paste

I want to pick an open-source replacement for Paste. 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. - CopyQ: CopyQ is a free program for Windows, macOS and Linux that saves everything you copy to the clipboard in a searchable history, so you can paste older items again. It is for anyone who copies and pastes often and wants a list of past copies. [Easy setup; Windows · Mac · Linux; replaces partly; GPL-3.0; https://github.com/hluk/CopyQ] - Maccy: Maccy is a free clipboard manager for Mac computers. It keeps a history of everything you copy so you can search and reuse earlier items. [Easy setup; Mac; replaces partly; MIT; https://github.com/p0deje/Maccy] - Ditto: Ditto is a free Windows program that keeps a history of everything you copy, so you can get back older items later. It is for Windows users who copy and paste a lot and want more than the single item the standard clipboard holds. [Easy setup; Windows; replaces partly; GPL-3.0; https://github.com/sabrogden/Ditto] - ClipCascade: ClipCascade keeps the clipboard the same across your computers and phones, so text, images, or files you copy on one device can be pasted on another. It is for people who use several devices and want to share copies between them, either through a server they run themselves or a public community server. [Easy setup; Windows · Mac · Linux · Android; replaces partly; GPL-3.0; https://github.com/Sathvik-Rao/ClipCascade] 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/clipboard.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/clipboard.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:
