rmcl review
An open-source, cross-platform launcher for terminal-oriented Minecraft users.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
rmcl is an open-source Minecraft launcher built around a terminal interface. Written in Rust, it supports vanilla Minecraft alongside Fabric, Forge, NeoForge, and Quilt. Separate instances help keep installations and configurations distinct, while Microsoft and offline account support covers two authentication paths. With builds for Windows, macOS, and Linux, rmcl is aimed at users who prefer command-line workflows and want a launcher that can handle both unmodified and modded Minecraft.
Its ecosystem coverage is a major strength. rmcl can browse Modrinth and CurseForge modpacks, import packs from Modrinth, CurseForge, MultiMC, Prism, and GTNH, and check modpack and content updates. That combination gives users several ways to bring existing setups into the launcher rather than tying them to one pack format. Microsoft authentication is also supported, and Java is selected automatically when no Java path is configured. The open-source model keeps the product distinct from launchers organized around paid tiers or subscription plans.
The standout feature is the combination of isolated instances and broad pack handling in a terminal-first workflow. Users who regularly switch between loader types, imported packs, or separate Minecraft configurations should find that focus relevant. rmcl is less suitable for players who expect a graphical interface, or for those who want modpack browsing beyond Modrinth and CurseForge. Choose it for cross-platform, open-source control over multiple Minecraft environments; choose an alternative if visual navigation is more important than terminal operation.
