Overlay overview

Premium — Operator and Overlord. Guests of a Premium owner inherit overlay access for that owner's servers.

The overlay is a small Tauri app that runs alongside Rust. It paints a transparent, always-on-top window in the corner of your screen showing:

• Your character position.
• Every teammate (online green, offline grey).
• Live world events (Cargo, Heli, Chinook, Oil Rig activity).
• Death markers (red cross, 30 min fade).
• Tags (!tag Raid, !tag Friendly, etc).
• Train tunnel entrances + monuments.

By default the overlay is click-through, so accidental clicks pass through to Rust. Press F9 to make it interactive (drag to move, click to inspect), F9 again to make it pass-through.

Pairing

The overlay pairs once via Steam OpenID. Your default browser opens, you confirm in Steam, the overlay finishes setup automatically. The resulting device token is stored locally via @tauri-apps/plugin-store and re-used on every launch.

See Install & pair.

Why Tauri

• Smaller binary (~5MB on Windows vs ~80MB Electron).
• Lower memory footprint while you're playing Rust.
• Real native always-on-top + transparency, including on Windows fullscreen-borderless.

Multi-server

In v1 the overlay shows one server at a time, picked from a dropdown. The roadmap has multi-overlay (one floating window per paired server).

Platforms

• Windows 10 / 11 — primary platform, signed installer.
• macOS — works in dev, needs Apple Developer notarisation for retail.
• Linux — AppImage builds; transparency is X11/Wayland dependent.

Limits

• Rust must run windowed-borderless (or windowed). Exclusive fullscreen blocks every overlay, same as Discord / CrosshairX.
• You need an active Operator+ subscription OR be a guest of someone who has one.
