Minecraft: just create modpacks?

I like to play with mods. However, I prefer variants such as those available on Twitch. You can simply click on a mod there and a modpack will be created. However, Twitch no longer works for with. Does anyone know of any alternatives? TechnikLauncher I don't think it's that good. Heavy modpack creation and many pre-built ones don't work.

I would spontaneously think of the ATLauncher.

otherwise, as far as I know, you can still tinker with MMC because you can also store multiple instances. You have to load and insert the mods manually.

I just use forge or 9minecraft
