Portal Launcher
What Portal Launcher is
Portal Launcher is a free, open-source Minecraft launcher for Linux, macOS, and Windows. It lets a host publish a modded instance so friends can synchronize mods, configurations, pack artwork, and Minecraft or loader-version changes before playing. Shared packs use Modrinth Shared Instances, allowing friends to join through the official Modrinth App even when Portal is installed only by the host. A Modrinth friends panel shows online contacts, handles requests and invites, and lets you join a friend’s game. Portal browses Modrinth and CurseForge mods with galleries, download counts, versions, changelogs, and compatibility filters. Before updating mods, it creates snapshots for reverting the last update and checks for missing dependencies. The launcher also offers a built-in modpack catalog, multiple mod-loader support, automatic updates, duplicate-mod detection, pack-update notifications, live server status, Discord Rich Presence, and instance importing from other launchers. It can read Prism Launcher’s data folder to carry over instances, accounts, and settings. Portal requires a genuine Minecraft account through Microsoft sign-in. The code is GPL-3.0-only licensed, and the project directs support requests to GitHub issues.

Portal suits Minecraft players who share modded instances with friends and want synchronized packs across Linux, macOS, or Windows. It also fits users moving from Prism Launcher or browsing mods from both Modrinth and CurseForge.
