Rating: 3.5/5 — Diverse traditions represented with genuine calculation depth. BaZi dominates by community interest, Western astrology has solid Swiss Ephemeris foundations, tarot has proper randomization, and I Ching has a culturally faithful Rust implementation. Most servers are individual projects — the commercial tier is where the real feature density lives.
