Crystal Launcher vs Spectra Launcher

Crystal Launcher has no write-up on Specifiction yet; its figures are above.

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.
