SCOPENET

A fast, fully customisable Minecraft launcher — and the self-hosted admin panel that controls it.

Brand it, publish vanilla versions or modpacks, manage players, and push changes to every launcher instantly.

What's inside

Launcher (Windows)	Tauri 2 + Rust + Svelte. Uses the system WebView2 instead of bundling Chromium, so the installer stays small and memory use low.
Admin panel (Docker)	Rust (Axum) + SQLite + Svelte. 14 MB image; measured ~2 MB RAM at idle.
Engine	scopenet-core: installs Minecraft, Java, Fabric/Quilt/Forge/NeoForge and launches the game.

Launcher features

• Accounts — private panel accounts (username + password, authenticated online-mode servers), and local offline usernames for local play. Tokens are encrypted with a key stored in Windows Credential Manager.
• Instances — every instance the admin publishes shows up in the sidebar; group-restricted ones only for the right players.
• One-click play — downloads the right Java automatically, the game, the mod loader and the modpack, with live speed/ETA. Files are shared between instances and verified by SHA-1.
• Built-in server — the instance's server is added to the multiplayer list, auto-joined (Quick Play on 1.20+), and its live status (players, MOTD, ping) is shown on the home screen.
• Settings — memory with a recommendation for your PC, resolution, fullscreen, what happens on launch, Java path, GC presets (G1 / ZGC), JVM args, Minecraft keybind editor (applied to every instance), custom accent colour, glass/animation toggles, UI scale, storage manager, per-instance overrides.
• Quality of life — game console, crash dialog with plain-English hints, repair files, offline launch from cache, self-updates from GitHub Releases, single-instance window, Ctrl+Enter to play.
• Branding from the panel — name, logo, colours, font, corner radius, glass, image/video background, news feed, social links, custom CSS. No rebuild needed.

Admin panel features

• Instances — pick a Minecraft version + loader, or import a modpack from Modrinth, CurseForge or a .zip (.mrpack, CurseForge export, or any instance folder). Upload extra mods/configs. CurseForge mods that block third-party downloads are flagged with a download link.
• Access control — public, signed-in players, or specific groups.
• Players — create/approve/disable accounts, roles, groups; sign-ups closed / approval / open.
• Launcher design — every branding option with a live preview and 7 colour presets.
• Dashboard — launches per day, active players, popular instances, recent activity.

Quick start

1. Run the panel

curl -O https://raw.githubusercontent.com/scopeddlol/SCOPENET-MC/main/docker-compose.yml
curl -o .env https://raw.githubusercontent.com/scopeddlol/SCOPENET-MC/main/.env.example
# edit .env → set ADMIN_PASSWORD
docker compose up -d

Open http://your-server:8080, sign in as admin, then:

1. Launcher design → name, logo, colours, news.
2. Instances → New instance → a version, or a Modrinth / CurseForge / .zip modpack.
3. Settings → how players sign in.

Put the panel behind HTTPS (Caddy, Traefik, nginx, Cloudflare Tunnel…) before sharing it. See docs/admin-guide.md.

2. Build your branded launcher

1. In GitHub → Settings → Secrets and variables → Actions → Variables, add:
   • PANEL_URL = https://panel.example.com (players connect automatically)
   • LOCK_PANEL = 1 (optional: hide the "change server" option)
   • LAUNCHER_NAME = MyServer Launcher (optional)
2. Actions → Release → Run workflow, enter a version like 1.0.0 — or push a tag v1.0.0.

The workflow builds the Windows installer, pushes the panel image to GHCR (ghcr.io/<owner>/scopenet-mc-panel, amd64 + arm64) and publishes a GitHub release. Installed launchers pick up new releases automatically.

The GHCR package is private by default the first time — make it public under your GitHub profile → Packages if you want docker pull without logging in.
