Built a Monte Carlo simulation platform for country-level macro scenarios

I'm a data scientist who spent years building forecasting models. The biggest lesson: single-point forecasts are almost useless for long-horizon structural questions. What matters is the distribution.

So over the past year I built WorldSim. It runs Monte Carlo simulations for 195 countries across multiple socio-economic indicators, producing full P10/P50/P90 probability distributions instead of single estimates. 100+ coupling rules connect variables causally, so shocks cascade realistically.

Stack: Django, PostgreSQL, Celery, Stripe. Deployed on Hetzner.

Free tier available (3 runs).

Would love feedback from anyone in the macro/economics space. Try the country you live in: worldsimlab.com
