Why Prism Launcher Is Better

|---|---|---|

| Mod support | CurseForge + Modrinth | Limited |
| Microsoft login | Yes | Questionable |
| Community trust | High | Low |

Why TLauncher Is Problematic
Security Concerns
TLauncher has been reported to bundle telemetry software and potentially unwanted programs. Multiple security researchers have flagged it.
Piracy Association
TLauncher allows playing Minecraft without purchasing the game. This violates Mojang's EULA and is considered piracy.
Server Compatibility
Players using TLauncher in offline mode cannot join servers that require authentication. Most legitimate servers require Microsoft authentication.
Trademark Issues
The original TLauncher project (TL Legacy) was taken over by a different entity. The current TLauncher is not the same as the original community project.
Recommended Alternative
Use Prism Launcher with a legitimate Microsoft/Minecraft account. It provides:
- Full mod management (CurseForge and Modrinth)
- Open source transparency
- Multi-instance management
- Full server compatibility
- No security concerns
