minecraft-launcher
Privacy-first Minecraft launcher. No telemetry. No Microsoft account requirement. Runs smooth on hardware that stock Minecraft chokes on.
Why this fork exists
Stock Minecraft phones home. Stock launcher pushes Microsoft accounts. Stock client struggles on low-end machines.
This fork fixes all three.
| Stock launcher | This fork | |
|---|---|---|
| Telemetry | Yes | None |
| Microsoft account | Required | Optional, never enforced |
| News fetch on launch | Yes | Hidden, no startup call |
| Plays on weak hardware | Often won't | Yes |
| Window title | Mojang branding | racked.ru launcher |
Full diff: CHANGELOG.md.

Trust
This is open-source. Verify the privacy claims yourself:
- docs/NETWORK_AUDIT.md — every network endpoint listed, telemetry verdict
- docs/SETTINGS_AUDIT.md — default-value diffs vs upstream
- docs/BLOAT_AUDIT.md — what was stripped, why
You don't have to trust me. Read the source.
