Watching or listening together online

I want to pick an open-source replacement for Teleparty, Watch2Gether (watch parties and synced playback with friends). 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. - Neko: Neko is a self-hosted virtual browser: a web browser running on a server that you open in your own browser window, with video streamed to you. It is for people who want to browse or watch videos together with friends, or run a shared browser session for teams. [Advanced setup; runs on a server you set up; replaces fully; Apache-2.0; https://github.com/m1k1o/neko] - CyTube: CyTube is a website where people create channels to watch videos from sites like YouTube together, with playback kept in sync for everyone in the channel. It is for groups of friends or communities who want to watch and chat together online. [Advanced setup; In your browser; replaces fully; MIT; https://github.com/calzoneman/sync] - Syncplay: Syncplay keeps video playback in sync across several people's media players over the internet, so everyone pauses, plays and jumps together. It is for friends or groups who want to watch the same video at the same time and chat while they watch. [Easy setup; Windows · Mac · Linux; replaces partly; Apache-2.0; https://github.com/Syncplay/syncplay] 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/watch-together.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.
