Matrix queries before you deploy

Prism Launcher is a GPL-3 Minecraft control plane built with Qt. It routes multiple instance nodes, Microsoft accounts, mod lanes, and modpack deploys — each setup in its own shell.

Yes. The launcher is GPL-3 free software. Minecraft still requires a legal license for authenticated multiplayer.

Prism continues the MultiMC-derived community line after the PolyMC fork. Active maintenance and 11.0.3 builds ship under the Prism name — prefer current releases over stale forks.

No. Prism is an independent community project with no affiliation to Mojang Studios or Microsoft.

SmartScreen scores binary reputation — unsigned community builds often trigger it. A prompt is not malware proof. Verify you pulled 11.0.3 from the official channel, then follow the SmartScreen diagnostic route if you trust the file.

Yes. Flatpak (~40 MiB) ships beside AppImage on the deployment console. Pick the packaging channel your distro prefers.

Yes. Use Add instance → MultiMC-compatible import. After migration, rebind Java settings and accounts on each imported node. See diagnostics for the numbered route.

Build 11.0.3 improves offline authentication routing for setups that need it. Standard Microsoft login remains required for normal authenticated multiplayer.

For modern authenticated multiplayer, yes. Prism stores session tokens locally so you can switch profiles across instance nodes.

Release 11.0.3 patches CurseForge CDN and API issues from July 2026. Update if pack downloads stalled on older builds.

Forge, Fabric, Quilt, and NeoForge run as separate loader nodes alongside vanilla shells. Mods must match both loader and Minecraft version of that instance.

GPL-3 source is public for audit. Pull official builds, compare checksums when published, and read the trust protocol. You remain responsible for third-party mods and packs you route through the launcher.

Yes. The MSVC channel targets Windows 10 and 11. Missing MSVCP140? Install Visual C++ 2022 redistributable first.

Windows, macOS, and Linux. The deployment console lists MSVC (~22.8 MB), DMG (~42.7 MB), AppImage (~102.6 MB), and Flatpak (~40 MiB) channels for 11.0.3.
