The record

Purpose: Portal Launcher is an open-source Minecraft launcher for sharing and automatically syncing modpacks with friends.
Shared packs: Hosts can publish instance updates, and friends’ copies sync mods, configs, pack icons, and Minecraft or loader version changes before play.
Interoperability: Shared packs use Modrinth Shared Instances and can be joined from the official Modrinth App, so only the host needs Portal.
Friends: The launcher includes a Modrinth friends panel for seeing online friends, sending requests and invites, and joining what a friend is playing.
Mod browsing: Portal browses Modrinth and CurseForge mods with galleries, download counts, versions, changelogs, and instance compatibility filtering.
Update rollback: Before mod updates, Portal takes snapshots so users can revert the last mod update, and its review warns about missing dependencies.
Other features: The launcher includes Discord Rich Presence, live server status, duplicate mod finding, modpack update notifications, and importing instances from other launchers.
Sharing limitation: Mods hosted on Modrinth sync by reference, while files from other sources are re-uploaded on each shared-pack push.
Login requirement: Portal requires a genuine Minecraft account through Microsoft sign-in and offers no offline or alternative authentication.
Privacy: Portal says it has no telemetry, analytics, or ads and uses Microsoft’s device-code sign-in without receiving the user’s password.
Build verification: Every release ships a SHA-256 checksum, and releases from version 1.0.6 onward carry GitHub build provenance attestations.
Support: The project directs bug reports and suggestions to its GitHub issue tracker.
License: The launcher code is licensed under GPL-3.0-only.
Compatibility: Portal reads Prism Launcher’s data folder so existing instances, accounts, and settings carry over.
