Our verdict on Justice Client

Justice Client is a free, open-source Minecraft launcher for players on Windows and Linux who want mod management, performance features, and social tools in one application. It supports Fabric, Forge, NeoForge, and Vanilla versions from 1.8.9 to 1.21.x. The launcher includes Java, supports shader installation and selection, and provides friends, direct messages, party invites, online status, and points redeemable for capes, wings, and shields.

Its strongest fit is mod-focused play across multiple loader types. Players can search Modrinth and CurseForge, then install, update, and toggle mods within each profile. Built-in performance mods target FPS improvements, while bundled Java removes the need to source a separate runtime. Shader selection adds another layer of customization. The main limitation is that Justice Client does not provide separate instances, modpack import, or built-in modpacks, so players who organize large modded setups around those workflows may prefer another launcher.

The social layer gives Justice Client a distinct focus among launchers: users can manage friends, send direct messages, invite others to parties, and display online status. Its free plan includes performance mods, Modrinth and CurseForge search, and Java, with no paid tier described. Windows and Linux downloads are supported, while macOS support is in development. Choose Justice Client if free mod search, per-profile controls, bundled Java, and social features match your priorities. Choose an alternative if you need separate instances, modpack importing, built-in modpacks, or automatic updates.
