Rust → WebAssembly

Simulation core

All combat calculations, movement validation, trade resolution, and economic ticks run in native-speed Rust compiled to WASM via wasm-pack

MapLibre GL

Interactive world map

Vector tile rendering with PMTiles, globe projection, smooth zoom and pan

D3.js + TopoJSON

2D map and data layers

Province boundaries, country outlines, city markers

Three.js

3D terrain relief

Optional elevation-based terrain rendering

Supabase

Auth and database

User profiles, XP tracking, multiplayer state sync

PMTiles

Map tile format

Self-contained vector tiles served from a single file, no tile server required

How to Self-Host

Politscape is a standard Next.js application. Self-hosting requires Node.js 18+ and optionally Supabase for auth and multiplayer.

Rust simulation

Improve combat modifiers, movement rules, naval mechanics, or economic ticks in /src/

Frontend / UI

React components in /components/, game scripts in /public/assets/js/

Map data

Province adjacency, sea regions, trade routes, terrain elevation — build scripts in /scripts/

Game balance

Unit stats, research costs, economic parameters — open an issue to discuss before changing
