Notes
Hammer can only be used on clients.
Hammer utilizes mrpack’s environment feature. Mods are either determined client-side, server-side, or both, which is carefully chosen based on overhead, purpose, and relevance.
If you install Hammer through a launcher, such as Prism Launcher or the Modrinth App, it will only install the mods that are marked as client-side or both-side.
