# Ex Compatibility — free Vedic astrology calculator

Both charts, read in full. What actually clicked, where it cracked. 🔍

Ex Compatibility is one of 40 free instruments on Supastro. It runs without a subscription and computes from the same NASA JPL-based engine as the paid product.

## What it does

Drop both birth details for an honest, chart-based autopsy — your Moon axis, Venus–Mars chemistry, Sun–Moon warmth, 7th-house pull and Darakaraka, weighed together (not a guna-milan gimmick). No fabricated drama, just the real wiring.

## What it costs

Nothing. Ex Compatibility is free and needs no subscription. Supastro publishes 40 free instruments in total.
