Hackstr
The GOAT for No Nonsense Modded Minecraft
One of the best open-source minecraft clients out there! Downloading mods is painless and easy. You can choose to search and download from both Modrinth and Curseforge, and it'll automatically download any dependencies the mods you've chosen might need. The UI is clean and readable, it has support for an insane amount of languages, it starts up near instantly, It's amazing. I could not IMAGINE using a different, ad infested, corporate owned, extremely bloated launcher after this.
