JyotishHub is a free Vedic astrology toolkit — Kundli chart generator, daily Rashifal, numerology, and compatibility matching. No login, no paywall. What's different: instead of wrapping a third-party API, I built the calculation engine myself in TypeScript using astronomy-engine — real sidereal positions, ascendant via spherical trig, Vimshottari Dasha, and yoga detection that follows the classical rules precisely (e.g. Gaja-Kesari checked from Moon, not Lagna, unlike many calculators).
