Trust & security
Open source — inspect what powers the portal
Source visibility, licensing, package integrity, and what stays on you as the traveler. prism-launcher.org is a community mirror — not the official prismlauncher.org project site.
License
GPL-3 terms in plain language
You may run, study, share, and modify Prism Launcher under GPL-3. Redistributed builds must preserve the same freedoms for downstream travelers.
The license covers the gateway software. Minecraft assets, Mojang services, and third-party mod shards keep their own terms.
Ethics & mirror notice
Project stance
Prism Launcher focuses on user freedom and honest redistribution. It does not claim Mojang endorsement. This domain (prism-launcher.org) is a community mirror — not operated by the official prismlauncher.org project team. Downloads link to GitHub release assets with published checksums.

Definitions
Gateway trust grid
- Mirror
- prism-launcher.org is a community mirror. Official project site: prismlauncher.org. Not run by the core Prism Launcher team.
- Source
- Public GPL-3 repository so skilled travelers can audit changes between crossings.
- Builds
- This mirror links to official GitHub release assets. Compare published checksums — avoid unknown third-party mirrors.
- Warnings
- SmartScreen and antivirus heuristics measure reputation. Signals, not final proof of malware.
- Mod shards
- Third-party jars live outside the launcher license. Vet packs like any executable content you import into a dimension.
- Accounts
- Microsoft login flows talk to Mojang or Microsoft services. Prism stores session data locally per dimension.
- Scope
- This mirror describes Prism Launcher. It does not replace legal advice or platform policy documents.
Malware clarification
What a flag usually means
Game gateways often trigger heuristic engines — they download libraries, spawn Java, and write dimension folders. A quarantine after an official install is commonly a false positive. Restore carefully and re-check hashes. See Guides for antivirus steps.
Your responsibility
What stays on you
- Comply with the Minecraft EULA and local law.
- Only install mod shards and packs you trust into each dimension.
- Back up worlds before large pack crossings or updates.
- Do not share account credentials in logs or screenshots.
