so many launchers to pick from! i personally like Modrinth the most

oh yeah and most of those launchers allow for easy modding. want a modpack? click install, wait for it to download, and then just click play in the automatically created instance. want only a few mods but don't want to check endless dependency lists? what is it 2015? also just click install, the launcher will automatically download dependencies (and the right versions of them too!). worry that you'll install a fabric version when you wanted forge? or a mod for 1.20 when you need 1.20.1? relax as when you click "add mods" the launcher automatically applies filters that only show you mods that are tagged for your specific version (filters that you can still disabled though, it doesn't lock you out of installing a mod that's not explicitly tagged as fit for your version, but you know it'll work on it)

though don't get too comfy slapping that install button, there're still two things that can't be automated - incompatibilities between mods, and straight up broken files. launchers nowadays significantly reduce the number of headaches you get when modding, but they don't entirely remove them lol

I'm kinda shocked you've never heard of them but yeah, there's unofficial third-party Minecraft launchers you can get. CurseForge, Modrinth, and Prism Launcher are the top 3 big ones everyone uses. I personally use Prism Launcher simply because it's the easiest to set up modpacks for imo.
