Lucerna
A clean, transparent, open-source Minecraft launcher. No telemetry. No adware. It never touches the Minecraft client.
What Lucerna does
Isolated instances
Every install is its own .minecraft — versions, mods, worlds, and JVM args never bleed across profiles.
Run your own server
Create, start, and diagnose a Minecraft server with a live console; export or upload it over SFTP.
Mod browser
Search Modrinth and CurseForge inside the launcher. Dependencies resolve automatically.
Transparent by construction
Every network request goes through one audited chokepoint with a static host allowlist. No telemetry, no fingerprinting, no hidden processes.
Every loader
Fabric, Quilt, Forge (1.7.10 → current), and NeoForge — installed in-process, no external wizard.
Built to be trusted, not just used
- Open source. GPL-3.0-or-later — forks must stay open, which blocks the re-skinned-with-telemetry forks Lucerna exists to avoid.
- No telemetry. No analytics, no fingerprinting, not even an opt-out variant.
- Never modifies Minecraft. The Java runtime and game files come straight from Mojang and are left untouched.
Download
Latest release: latest
Windows 10/11 (64-bit). Java is not required — Lucerna downloads the correct runtime per Minecraft version. Not code-signed yet: on first run, SmartScreen → “More info” → “Run anyway”.
