LiveSplitOne VS livesplit-one-desktop

https://one.livesplit.org livesplit in your browser

Sounds puzzling. Do you know about the browser version of Livesplit? Maybe that would work better for you.

If you download LiveSplit from the official site https://livesplit.org/ and get a zip folder (that you have to extract) there's absolutely no risk. You could also try https://one.livesplit.org/ (LiveSplit One) that doesn't even install anything on your computer, just runs entirely in a browser

Livesplit isn't a virus (https://twitter.com/wooferzfg/status/1300559588819902469?lang=en). However, it's a .exe, so you might not be able to run it on Mac products. You could use Livesplit One instead https://one.livesplit.org/. To get your Switch onto your computer, you'd need to get a capture card. I honestly don't know which ones work for Macs, so you'd need to do a bit of research.

A Speedrunning Browser Timer

If you have concerns, an alternative is the browser version, https://one.livesplit.org/.

You don't need to build from source afaict since they seem to provide a hosted version of it for you: https://one.livesplit.org/

...I guess one last thing is this program only works on PC, if you have a Mac (or chromebook or whatever) the timer selection is very sparse. Though you do have LiveSplit One that runs in a browser https://one.livesplit.org/

Instead, I wrote a little program called live-split-hotkeys. It reads hotkeys from your LiveSplit settings so you don't have to maintain hotkeys in two places, and it uses LiveSplit Server to talk to LiveSplit so it has no dependency on a particular display server. It has some important limitations which are described in the README, and hopefully one day it'll be made irrelevant by the desktop version of LiveSplit One, but for now I thought it could be useful to others.

You'll have to wait for livesplit one to properly release on desktop https://github.com/CryZe/livesplit-one-desktop

There is a prototype of a desktop version of livesplit one. It has no UI so you'll want to make your splits and layouts in the web version of livesplit one and export them. Everything has to be done through the config.yaml included in the repo.

FYI you can use LiveSplit One Desktop I haven't tested it on Linux yet but it works great on Mac, they haven't released the UI to configure it yet so you need to use the config file.
