# Unlucky Launcher (ULL)

|
||
|
||
Unlucky Launcher (ULL) is a free, open-source Minecraft: Java Edition launcher written in Rust
|
||
(Apache-2.0). It ships as one native binary per platform — no installer, no bundled runtime, no
|
||
WebView. The launcher embeds an AI agent client (chat / configuration / crash diagnosis) and can be
|
||
attached to other agent tooling as an MCP server.
|
||
|
||
- **Single-file native binary**: the launcher itself needs no JVM, no WebView and no sidecar
|
||
runtime. The JDK a game needs is downloaded and managed per instance, not as a launcher
|
||
dependency.
|
||
- **Two UI stacks during the rewrite**: the released UI is Slint (Royalty-Free 2.0); the
|
||
next-generation UI is iced 0.14 + Material 3 Expressive and is still being written (see Status).
|
||
- **CPU software-rendering fallback**: `--software-renderer` gives the full UI on machines with no
|
||
usable GPU or with broken drivers.
|
||
- **AI agent + MCP**: chat, setting edits and crash diagnosis inside the launcher; `ull agent
|
||
serve` exposes the same core as an MCP server (stdio or Streamable HTTP) to external agent tools.
|
||
- **Mod loaders**: Fabric, Quilt, NeoForge, Forge, with modpack and CurseForge / Modrinth clients in
|
||
the core.
|
||
- **Java management**: a Temurin → Oracle → Microsoft → Zulu fallback chain, region-aware.
|
||
- **Engine**: multi-source download (health scoring, mirrors, chunked transfers, hash while
|
||
downloading) and a YAML rule-based crash diagnosis engine.
|
||
- **License**: Apache-2.0 © AskaEth (YeiJ).
|
||
|
||
## Compliance statement
|
||
|
||
- **Microsoft sign-in only.** Authentication is Microsoft OAuth 2.0 device code flow → Xbox Live →
|
||
XSTS → `api.minecraftservices.com`, using the player's own Microsoft account and their own game
|
||
entitlement. There is no other account provider.
|
||
- **Credentials stay on your machine.** Account tokens are stored locally only, are never sent to
|
||
any server operated by this project, and the AI features cannot read them.
|
||
- **Offline profiles cannot play online.** A local offline profile performs no Microsoft
|
||
authentication, contacts no Microsoft/Mojang service, exists for local and isolated-network
|
||
testing only, and cannot join servers that check accounts against the official service.
|
||
- ULL does not distribute, mirror, proxy or modify any Minecraft game files.
|
||
- Not affiliated with Mojang or Microsoft.
|
||
|
||
## Status
|
||
|
||
Two tracks. They are not the same product yet, so read the headings before downloading anything.
|
||
|
||
### Track A — released: v0.1.0, Slint UI (this is what you can download today)
|
||
|
||
- **GitHub Releases `v0.1.0`** (2026-11-01, flagged pre-release): single-file assets for Windows
|
||
x64 (a bare `.exe`), Linux x64 and macOS (arm64 and x64) `.tar.gz`, plus `SHA256SUMS.txt` and
|
||
`LICENSE` / `NOTICE` / `README.md` as side assets on Windows.
|
||
- **UI**: Slint + Metro. This is the shipped GUI — the instance, download, account, Java, log and
|
||
settings pages drive the real engine (the in-app AI chat panel is a scripted placeholder).
|
||
- **CLI `ull`** ships in the same release and is fully usable: `instances`, `install`, `launch`,
|
||
`accounts`, `sessions`, `logs`, `diag`, `config`, `java`, `agent`.
|
||
- Windows ARM64 and Linux ARM64 slots are wired into the release pipeline; the next tagged release
|
||
builds them. The `v0.1.0` assets predate those two slots.
|
||
|
||
### Track B — in progress on `dev`: next-generation UI (iced + Material 3 Expressive)
|
||
|
||
**Nothing on this track is released, and no download contains it.** You can only see it by
|
||
building from source.
|
||
|
||
- **Locked direction**: the look is Material 3 Expressive and the framework is iced 0.14; the UI
|
||
layer is written from scratch. Neither the style nor the framework will change again.
|
||
- **Done**: the token crate `crates/design` (no UI framework, no third-party crates — real HCT
|
||
color, type scale, shape scale, spacing, elevation, motion, icon geometry, per-component
|
||
metrics) and the skeleton crate `crates/app-iced` (opens a window, self-drawn title bar and
|
||
window buttons, navigation rail, colors and type taken from tokens only, GPU→CPU backend probe
|
||
with automatic fallback, and the screenshot/diff channel the visual reviews use).
|
||
- **Not done**: the component library (buttons, dialogs, lists, menus, search, and the rest of the
|
||
M3 set), page migration, and the i18n pass. Every page in the iced binary is a placeholder.
|
||
- **Slint stays until the flip**: `crates/app` remains the reference implementation until the iced
|
||
build passes equivalence acceptance; only then is `unlucky-launcher-iced` renamed to
|
||
`unlucky-launcher` and the Slint crate retired.
|
||
|
||
Binaries in the workspace, so you can tell them apart:
|
||
|
||
| Binary | Crate | State |
|
||
|--------|-------|-------|
|
||
| `unlucky-launcher` | `crates/app` (Slint) | released in v0.1.0; still the usable GUI |
|
||
| `unlucky-launcher-iced` | `crates/app-iced` (iced 0.14) | under construction; skeleton only, not shipped |
|
||
| `ull` | `crates/cli` | released in v0.1.0; headless and fully usable |
|
||
|
||
## Module map
|
||
|
||

|
||
| `game` | version / instance repository, snapshots and inheritance resolution |
|
||
| `launch` | 10-stage launch pipeline, processes, JSONL event stream |
|
||
| `auth` | Microsoft sign-in / local offline profiles |
|
||
| `addon` | mod loader installation, modpacks, CurseForge / Modrinth |
|
||
| `diagnose` | five signal collectors, YAML rule engine, hs_err parsing |
|
||
| `platform` | OS abstraction: paths, processes, file locks, capability probing, runtime OS detection |
|
||
|
||
## Building
|
||
|
||
Prerequisites:
|
||
|
||
- Rust stable (`rust-toolchain.toml` selects the toolchain automatically; the gates also need the
|
||
`rustfmt` and `clippy` components)
|
||
- Windows: MSVC toolchain (what CI uses) or MinGW-w64 (`x86_64-pc-windows-gnu`)
|
||
- Linux: `libxkbcommon-dev libfontconfig1-dev libgl1-mesa-dev libegl1-mesa-dev libwayland-dev
|
||
libxcb1-dev` — needed by both UI stacks (Slint's winit + femtovg, iced's winit + wgpu/tiny-skia)
|
||
|
||
```bash
|
||
cargo fmt --all --check # formatting
|
||
cargo clippy --workspace --all-targets -- -D warnings # lints (zero-warning gate)
|
||
cargo test --workspace # tests
|
||
cargo build --release # binaries land in target/release/
|
||
```
|
||
|
||
What the build produces:
|
||
|
||
- `unlucky-launcher` — the Slint UI (the released one)
|
||
- `unlucky-launcher-iced` — the iced UI skeleton. The name is temporary: it can only become
|
||
`unlucky-launcher` at the flip, because two crates in one workspace cannot emit the same binary
|
||
name into the same target directory.
|
||
- `ull` — the CLI
|
||
|
||
Rendering switches:
|
||
|
||
- `unlucky-launcher --software-renderer` (equivalent to `SLINT_BACKEND=winit-software`) forces the
|
||
CPU path on the Slint build
|
||
- `unlucky-launcher-iced --software-renderer` forces tiny-skia (`ICED_BACKEND=tiny-skia`);
|
||
`--screenshot <png>` writes one frame and exits, which is the acceptance channel
|
||
- Both builds probe the backend at startup and fall back to CPU automatically when no adapter is
|
||
usable
|
||
|
||
Dependency license check (optional locally, required in CI):
|
||
`cargo deny check licenses bans sources`.
|
||
|
||
## CI gates
|
||
|
||
Every push runs fmt / clippy (warnings are errors) / the full test suite, plus a headless render
|
||
smoke on Linux and a macOS runtime probe. Nothing here is advisory: a red gate blocks the merge.
|
||
|
||
| Workflow | Content |
|
||
|----------|---------|
|
||
| `.github/workflows/ci.yml` | fmt + clippy + test + release build (Windows / Linux matrix); Linux runtime smoke (Xvfb: renders one real frame, then asserts the PNG is not blank); macOS runtime smoke |
|
||
| `.github/workflows/guards.yml` | zero-UI guard for `crates/core` (manifest plus `cargo tree`), 400-lines-per-file guard, cargo-deny license and source guard |
|
||
| `.github/workflows/release.yml` | tag `v*` → per-slot builds → single-file artifacts + `SHA256SUMS.txt` → GitHub Release |
|
||
|
||
## Platform baseline
|
||
|
||
Minimum baseline: **Windows 10**; Windows 8.1 / 8 / 7 are not supported.
|
||
|
||
- Windows 10/11 builds use the **standard toolchain** (MSVC / GNU) — no custom target specs, no
|
||
`-Zbuild-std`, no import-table allowlists
|
||
- macOS 12+ (Apple Silicon and Intel) and Linux x64 / arm64 are supported build slots; on Linux,
|
||
X11 is the preferred path today and Wayland is the long-term direction. macOS builds are unsigned,
|
||
so the first launch needs the Gatekeeper quarantine attribute cleared
|
||
(`xattr -d com.apple.quarantine`)
|
||
- Android Termux is experimental and not promised: CLI only, GUI unverified
|
||
- Platform independence is expressed through **separate test matrices**, not separate artifact
|
||
pipelines; capability differences use feature gates with runtime probing
|
||
- **Renderer fallback on both UI stacks**: the Slint build drops to software rendering, the iced
|
||
build drops from wgpu to tiny-skia, so a machine without a usable GPU still gets the full UI
|
||
|
||
## License and acknowledgements
|
||
|
||
- **This project**: Apache License 2.0, see [LICENSE](LICENSE); third-party notices in
|
||
[NOTICE](NOTICE).
|
||
- **Slint** (<https://slint.dev>), Royalty-Free 2.0: obligation for the Slint build that v0.1.0
|
||
ships — an `AboutSlint` widget on the about page (still outstanding) and, until it lands, the
|
||
NOTICE file, this section and a "Made with Slint" note on the release page. The obligation is
|
||
kept for as long as a Slint-linked binary ships.
|
||
- **iced** (<https://github.com/iced-rs/iced>), MIT: the framework of the next-generation UI,
|
||
together with `winit` and, through it, `wgpu` / `tiny-skia` (Apache-2.0 / MIT).
|
||
- **Google Material Color Utilities** (Apache-2.0): the color tokens in `crates/design` are a Rust
|
||
port of its HCT / ColorSpec2021 algorithms; details and the exact ported functions are listed in
|
||
[NOTICE](NOTICE).
|
||
- **Other major dependencies**: `rmcp` and `axum` (Apache-2.0 / MIT) for the MCP server, `tokio`
|
||
(MIT), `reqwest` with rustls (MIT / Apache-2.0), `serde` / `serde_json` (MIT / Apache-2.0),
|
||
`zip` / `flate2` / `tar` (MIT / Apache-2.0). The allow-list cargo-deny enforces is in `deny.toml`;
|
||
GPL-family dependencies may not enter the main line.
|
||
|
||
Thanks to [HMCL](https://github.com/HMCL-dev/HMCL) and
|
||
[PCL2](https://github.com/Meloong-Git/PCL) (both GPL-3.0) — those two old-timers have been riding
|
||
along with the overwhelming majority of Minecraft players for years now. This launcher learned an
|
||
enormous amount from them about how a launcher should feel and how it should work, and it exists
|
||
very much in their debt.
