Minecraft Speedrun Timer?

Hi, I've been playing Minecraft for a long time, and I often watch Minecraft on YouTube, Twitch, etc., and that's where I often see speed runs. And the speed runners have a timer, where is Nether in, Nether Out End in and so what. Is that a plugin for MC? Or is that an additional program for the computer? Or can you use that online? And how do you use that? Or download it?

The timers there are plugins so at bastighg the one from TheFabo is from yt

This is an additional program, or just an overlay. You can replace the text with whatever you want. Unfortunately I don't know what this program is called. If you find out, please write to me.

OK, where can you download this?

OK, someone will already know 👍

These are mostly server plugins that are self made but I could build you a timer with commands if you have server

I know Live Split, but I can't explain how it works, I've only used it once for a fun speed run

Yes, I know that with Basti, but that's not Speedrunn 😇

If you made them yourself, why are they always in exactly the same style?

I said mostly but do you have a server?
