[Showoff Saturday] Fake Database -free fake data generator with 120+ fields, correlation engine, 7 export formats

Built Fake Database (https://fakedatabase.com/) — a free, browser-based fake data generator.

**Technical highlights:**
- Cross-field correlation engine (40+ relationships) — data is internally consistent
- Semantic map (130+ entries) for automatic column type inference
- Web Worker for generating 5,000 records without blocking UI

**Technical highlights:**
- Cross-field correlation engine (40+ relationships) — data is internally consistent
- Semantic map (130+ entries) for automatic column type inference
- Web Worker for generating 5,000 records without blocking UI
- [u/dnd-kit](/u/dnd-kit) for drag-and-drop field reordering
- SheetJS for Excel export
- PWA with service worker for offline support
- Manual chunk splitting (xlsx, react, dnd-kit)
- Dual locale support (PT-BR / EN-US) with locale-aware data generation

**Why I built it:** Mockaroo charges $49/month for SQL/Excel export. Faker.js requires a backend. I wanted something free, browser-based, and with correlated data.

Stack: React 18, TypeScript, Vite
