After logout and re-login, the cloud save was never fetched because useAuthGate.init() had already run with an anonymous token. Now handleSetRegistered fetches and restores the cloud save when the user becomes registered, so they return directly to their game. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Token Empire
A browser-based incremental/idle game where you manage an AI company from a garage startup to building AGI. Navigate the real tensions of the AI industry: scaling compute, training frontier models, balancing safety vs capability, hiring talent, and competing with rival labs.
Target: 4-8 hour single playthrough | Platform: Desktop browser | Price: Free
Quick Start
# Prerequisites: Node.js 18+, pnpm 10+
pnpm install
pnpm dev
The web app starts at http://localhost:5173 (or the next available port). The backend server starts alongside it for cloud saves and leaderboards.
Tech Stack
| Layer | Choice |
|---|---|
| Frontend | React 19 + TypeScript, Vite |
| State | Zustand (slice pattern, localStorage persistence) |
| Styling | Tailwind CSS (custom dark theme) |
| Charts | Recharts |
| Backend | Hono (Node.js) |
| Database | PostgreSQL + Drizzle ORM |
| Monorepo | Turborepo + pnpm workspaces |

The game engine is fully decoupled from React. It runs identically for real-time ticks, offline catch-up, and testing.
Game Overview
Four Eras
- Startup (~30 min) — First datacenter, first model, first customers
- Scale-up (~2 hr) — Growth, multiple datacenters, specializations
- Big Tech (~4 hr) — Global operations, regulation, IPO
- AGI (~8 hr) — Endgame push, AI agents, custom chips
Core Loop
Buy GPUs → Allocate compute → Train models → Deploy → Earn revenue → Expand
Key Systems
- Infrastructure — Datacenters across 7 global regions with different costs, latency, and risks
- Research — Tech tree with generation upgrades and specialization branches
- Models — Train, tune, and deploy models with capability scores across reasoning, coding, creative, multimodal, and agents
- Market — Consumer subscriptions and B2B API with token-based pricing
- Talent — Four departments (Research, Engineering, Ops, Sales) with hiring and morale
- Competitors — AI rival labs with distinct personalities that react to your moves
- Events — 40+ events across industry, regulatory, PR, internal, market, and geopolitical categories
- Safety — Tradeoff between capability benchmarks and safety; low safety risks PR disasters
- Funding — VC rounds from Seed to IPO with dilution mechanics
- Achievements — 15 milestones tracking progression
Scripts
pnpm dev # Start all apps in development mode
pnpm build # Production build
pnpm typecheck # Type-check all packages
pnpm lint # Lint all packages
pnpm clean # Clean build artifacts
Backend Setup
The backend requires PostgreSQL for cloud saves and leaderboards. Set the connection string in apps/server/.env:
DATABASE_URL=postgresql://user:password@localhost:5432/token_empire
Run migrations:
cd apps/server
pnpm db:push
The game works fully offline without the backend — saves persist to localStorage.
