An Opinionated Launcher. Built for myself, If your its to your taste, help yourself.
I wanted a launcher that just played Minecraft.
What I changed vs upstream
| Stock launcher | Prism | This fork | |
|---|---|---|---|
| Telemetry | Yes | None | None |
| Microsoft account | Required | Optional | Optional, never nagged |
| News fetch on launch | Yes | Yes | Hidden, no startup call |
| Theme | Ugly | Clutered | AMOLED |
| Plays on weak hardware | Often won't | Yes | Yes (Java 21 bundled) |
Full diff in CHANGELOG.md. Per-endpoint network audit in docs/NETWORK_AUDIT.md.
What it does
- Modrinth, CurseForge, FTB, ATLauncher, Technic instance imports
- Bundled Java 21, no system install needed
- Portable: one folder, USB-friendly
- Offline mode: pick a username, play. Microsoft sign-in only if you actually need premium features
- Pure black/white theme, no chrome accents
That's it. Same scope as Prism, just narrower defaults.

Trust
Don't take my word on the privacy stuff. Read the audits:
- docs/NETWORK_AUDIT.md — every endpoint listed, telemetry verdict per call
- docs/SETTINGS_AUDIT.md — default-value diffs vs upstream
- docs/BLOAT_AUDIT.md — what got stripped, why
It's GPL-3.0. Source is right there.
Status
Personal project. I use it daily, that's the only QA. No support guarantees. Bugs happen. Use at your own risk.
PRs welcome but not promised to merge — this is opinionated by design.
License
GPL-3.0-only. Per-file copyright headers preserved.
Based on PrismLauncher (GPL-3.0), itself a fork of PolyMC and MultiMC.
