Precision in calculation.
Transparency in methodology.
Simplicity in experience.
Kundli.io was built to eliminate black-box predictions, fear-based astrology, and contradictory charts by combining classical Vedic principles with rigorous astronomical computation.
Why Kundli.io Was Created
Online astrology has become confusing and contradictory. A person enters their exact birth details on three different platforms and receives three incompatible charts. One site declares severe Mangal Dosha; another claims none exists; neither reveals the mathematical or astrological rules used.
Many tools mix Western tropical and Indian sidereal methods without disclosure, or rely on AI language models to fabricate sensationalized predictions that prey on human anxieties.
Kundli.io was built to solve this exact problem. We believe users deserve to know precisely how their chart is computed, which classical rules are applied, and where the boundaries of astrological interpretation lie.
Calculation Methodology & Technology
We maintain a strict separation between physical astronomical calculation and traditional interpretive frameworks:
Swiss Ephemeris Precision
Our engine calculates raw celestial coordinates using the Swiss Ephemeris (`swisseph-wasm`) and astronomy algorithms, matching the coordinates used in modern observational astronomy down to the arc-minute.
Lahiri Ayanamsa (Chitra Paksha)
We subtract the official Lahiri Ayanamsa to convert coordinates into the Sidereal (Nirayana) zodiac — following the standard established by the Government of India Calendar Reform Committee.
Parashari Classical Framework
House placements, house lord relationships, and Dosha evaluations adhere to foundational Vedic texts, notably the Brihat Parashara Hora Shastra, using classical Whole Sign Bhavas.
In-Memory Ephemeral Engine
Reports are generated in memory during your active web session. We do not maintain a central database of your birth information, protecting your complete privacy.
