Kundli Matching Online: 6-Layer Vedic Marriage Compatibility

AstroSutra's compatibility analysis goes beyond the standard 36-point Gun Milan / Ashta Kuta score that most kundli-matching tools stop at. The engine runs six layers of BPHS-compliant analysis on both partners' charts and produces a structured report — not a pass/fail label.

• Ashta Kuta matching — full 36-point Guna Milan with per-Kuta breakdown across Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, and Nadi.
• Mangal Dosha severity (0–10 scale) with classical cancellation rules — not a simplistic yes/no flag.
• Dasha Sandhi timing — whether the planetary periods around the proposed marriage window are stable for both partners.
• D9 Navamsha cross-check — the marriage chart, not the rashi chart, is what classical Jyotish weighs heaviest for long-term compatibility.
• Nadi Dosha cancellation — full rule set, including pada-level analysis.
• AI-narrated compatibility brief grounded in the deterministic computation above — never inventing numbers.

Same Swiss Ephemeris (NASA JPL) engine that powers the rest of AstroSutra. Pricing starts at $5 per match. See worked examples on the celebrity kundli matching page for how the six layers compose into a real recommendation.
