Features

Dashboard
Status Dashboard
At-a-glance summaries of bases, fleet, contracts and cash. Drill down to full views.
Layout
Customisable Layout
Drag panels to reorder your Status tab — bases, fleet, contracts and empire burn. A pinned company panel and attention bar stay up top.
Detail
Detail Views
Tap any base, ship or contract for a full sheet — production lines with live ETAs, a per-building repair gauge, ship cargo and fuel, plus dependency-aware contract conditions.
Bases
Base Status
BURN / REPAIR / PROD indicators per base: days of supplies left, days since last repair, production utilisation. RED/YELLOW/GREEN filters match any indicator.
Burn
Burn Tracking
Per-site and empire-wide material burn rates with urgency indicators. The empire rollup sorts by type, status or ticker. Purchase need calculation with resupply targets. Configurable thresholds.
Fleet
Fleet Overview
Ship status, destinations, ETA countdowns, cargo and fuel bars.
Contracts
Contract Monitoring
Active contracts with condition status and deadlines.
Company
Company & Liquidity
Company identity and cash balances, primary currency first.
Data
Staleness Indicators
Every data surface shows its source (live / FIO / cache) and age. Burn numbers from stale data are worse than none — APXM never hides how fresh its data is.
Themes
UI Themes
Five presets shared with Helm — PrUn, DryDock, CRT, Vivid, Colorblind — including a CVD-safe status palette.
Data
FIO Integration
Auto-fetches data from the FIO REST API on startup if credentials are configured.
Interface
Buffer Refresh
Per-site data refresh without switching back to APEX.

How It Works

APXM intercepts the WebSocket connection between APEX and the game server using a main-world content script injected before Prun loads. Messages are decoded through Socket.IO's double-encoding layer (engine.io + socket.io framing) and fed into typed Zustand stores. The React overlay renders from those stores.

The interception and message bus code lives in @prun/link, a shared library from the 27Bit toolset (private). APXM observes and displays — it never sends messages to the game server.
