Spectra Launcher vs X Minecraft Launcher

Spectra Launcher is a free desktop launcher for starting Minecraft and keeping multiple installations separate. Each instance has its own Minecraft version, mods and worlds, and supports Vanilla, Fabric, Quilt, Forge and NeoForge. The launcher can browse and install mods, shaders, resource packs and modpacks from Modrinth and CurseForge, including their required dependencies. Players can sign in with Microsoft/Xbox or offline accounts; Spectra finds and installs the required Java version automatically. It also imports instances from Prism, CurseForge and the Modrinth app, and exports them as .mrpack or .zip files. Shared views collect worlds and screenshots, alongside 3D skin previews, saved skins and cape switching. Other tools include Quick Play for Minecraft 1.20+, server status with player counts and ping, live logs, crash-report sharing, optional Discord status and playtime tracking. Downloads are listed for Windows, macOS and Linux. Spectra says accounts, settings and instances stay on the user's computer, and Microsoft/Xbox passwords are not seen by the launcher.

X Minecraft Launcher (XMCL) is a free, open-source launcher for managing Minecraft game resources and separate game instances. It runs on Windows, macOS, and Linux. Users can manage modpacks, resource packs, mods, shader packs, and other resources, with instances covering Forge, Fabric, Quilt, NeoForge, OptiFine, and LabyMod; Bedrock support is experimental. Its marketplace gathers modpacks and projects from Modrinth, CurseForge, and FTB. The launcher can import modpacks, manage Java runtimes, and update automatically. Mod tools include dependency inspection and custom groups. Account options include Microsoft, offline, Ely.by, and LittleSkin authentication. World tools let users preview saves, select, copy, or delete chunks, and view structures in 3D. Users can export modpacks and local server files from the launcher. Telemetry is off by default and is processed only if enabled in settings. XMCL says it does not handle Microsoft account passwords, credentials, or session tokens. It is an independent project and is not an official Minecraft product or associated with Mojang or Microsoft.
