Overview

Helm galaxy overview
Resource filter highlighting systems
System view with planets
Planet detail panel with resources and CX distances
Route planner with highlighted path

Features

Resources
Resource Filter
Pick a material and Helm shows the way. Every system with that resource gets highlighted and shows the concentration factor. Useful for scouting base locations without opening 40 PLI buffers.
Navigation
Route Planner
Quickly highlight the shortest path between any two systems, gateway-aware. Jump count included.
Market
CX Distances & Prices
Every system panel shows jump count to all 6 CX's with gateway use flagged. Available resources shown with the most recent ask price at that nearest CX (via FIO).
Detail
Planet & System Data
Detail panels for every system and planet. Resources, environment, fertility, gravity, temperature — plus infrastructure data showing population tiers, happiness and more. Planet panel links directly to PRUNPlanner for base planning.
Search
Search Everything
Type-ahead across systems and planets — name, natural ID, substring, whatever. Searching for a planet drops you straight into its system view with the target highlighted.
Map
Gateway & Settled Overlays
Toggle Gateway links on and off. Settled systems overlay shows where bases already exist with fancy pants animations.

Data Sources

All data comes from the public FIO REST API, fetched client-side on load. Gateway connections have no API endpoint — maintained manually.

Privacy

Helm is a static site. It fetches public game data on load, renders locally and stores nothing server-side. No backend, no auth, no tracking.

Tech Stack

Pixi.js 8 — WebGL 2D rendering pixi-viewport — pan / zoom / pinch TypeScript 5.7 — strict mode Vite 6 — build & dev server Cloudflare Pages — hosting
Also Powers APXM

Helm is packaged as a library and embedded inside APXM — the empire HUD extension for Prosperous Universe. The desktop mode overlays your bases and ships live onto the universe map.

Helm is inspired by and built on the shoulders of giants — it wouldn't exist without the work that came before it.
