Free Vedic Kundali Matching & Marriage Compatibility Analysis
Astro Marriage is a free, privacy-first Vedic astrology platform that analyzes birth charts (Kundali / Janam Patri) to assess marriage compatibility, predict marriage timing, describe future spouse characteristics, and provide personalized remedies. Unlike basic matching tools, it combines four classical Vedic systems — Parashari, KP (Krishnamurti Paddhati), Jaimini, and Bhrigu Nandi Nadi — for deeply accurate analysis. All planetary calculations use the Swiss Ephemeris (JPL DE431 accuracy) compiled to WebAssembly and run entirely in your browser — no birth data is ever sent to a server.

Ashtakoot Milan (also called Gun Milan) is the traditional Vedic method for evaluating marriage compatibility. It scores 8 dimensions (Kootas) based on the Moon's Nakshatra placement in each partner's chart:
| Koota | Points | What It Measures |
|---|---|---|
| Varna | 1 | Spiritual and ego compatibility — Brahmin, Kshatriya, Vaishya, Shudra classification |
| Vashya | 2 | Mutual attraction and dominance — who influences whom in the relationship |
| Tara | 3 | Destiny and health compatibility — based on Nakshatra count (9 Taras cycle) |
| Yoni | 4 | Physical and sexual compatibility — 14 animal Yoni types with compatibility matrix |
| Graha Maitri | 5 | Mental and intellectual compatibility — friendship between Moon sign lords |
| Gana | 6 | Temperament matching — Deva (divine), Manushya (human), Rakshasa (demon) |
| Bhakoot | 7 | Emotional compatibility, love, prosperity, and family happiness |
| Nadi | 8 | Genetic and health compatibility — Vata, Pitta, Kapha constitution matching |
Score interpretation: Below 18/36 — not recommended. 18-24 — acceptable. 25-30 — good match. 31-36 — excellent compatibility. Astro Marriage also applies Nadi Dosha, Bhakoot Dosha, and Gana Dosha cancellation rules that reduce false negatives by up to 40% compared to basic calculators.
Astro Marriage uses a multi-system convergence approach — when 3 or more methods agree on a time period, it creates a high-probability marriage window:
Mangal Dosha occurs when Mars is in the 1st, 4th, 7th, 8th, or 12th house from the Ascendant, Moon, or Venus. While ~40% of people have some form, Astro Marriage applies 15+ classical cancellation rules automatically — only 10-15% have truly active dosha after analysis. Cancellations include: Mars in own sign (Aries/Scorpio), Mars exalted (Capricorn), Jupiter aspecting Mars, both partners being Manglik (mutual cancellation), and house-specific exceptions from Brihat Parashara Hora Shastra.
Most Kundali matching websites stop at Ashtakoot Milan score and Mangal Dosha. Astro Marriage goes far deeper with analysis modules that no competitor provides:
True compatibility goes beyond matching Nakshatras. Our synastry engine places each partner's 9 planets into the other's 12 houses (both directions — A-in-B and B-in-A) to reveal how you actually affect each other's life areas. It also calculates Navamsa (D9) overlays — placing D1 planets into your partner's D9 marriage chart — revealing soul-level, karmic impacts invisible to surface analysis. Planetary conjunctions within 10° orb identify Venus-Mars passion, Moon-Moon emotional attunement, Jupiter-Moon soulmate connections, and Saturn karmic bonds.
No astrology tool tells you the hard truth about divorce risk. Ours does. We analyze 12+ divorce indicators from classical texts: 7th lord in dusthana houses (6th, 8th, 12th), separative planets in 7th house, 2nd house (Mangalya Bhava) affliction, 6th/8th lord entering 7th house, debilitated 7th lord, Venus in dusthana, Mars-Saturn conjunction in 7th, and more. A protective buffer (Jupiter aspects, strong 7th lord, benefic influences) is deducted from the raw score to give a realistic probability with level classification (low / medium / high / very high).
Goes beyond simplistic "Venus-Mars = affairs" with a sophisticated three-layer model: (1) Capacity & History — innate passion drive (Venus-Mars conjunction, Rahu-Venus desire amplification, 5th house romantic nature), (2) Opportunity & Triggers — external circumstances enabling extramarital connections (5th/8th/11th/12th house activations, 3rd house communication patterns), (3) Stabilizers & Moral Anchors — factors preventing infidelity (Saturn discipline, Jupiter morality, strong 7th lord loyalty). The final score balances all three layers with protective factor deductions.
The only Kundali matching tool that provides both sexual compatibility between partners and individual sexual health indicators. Compatibility uses the 14 Yoni animal system with a full 14×14 compatibility matrix, drive assessment, and intimacy scoring. Sexual health analysis covers male-specific indicators (PME risk from Venus-Mars/Venus-Ketu conjunctions and fire sign placements; ED risk from debilitated Sun, Saturn-Mars aspects) and female-specific indicators (frigidity risk, physical comfort assessment) — with gemstone and lifestyle recommendations.
A lifetime scan of Mahadasha-Antardasha periods that identifies exact years when your relationship faces maximum stress. The engine identifies risk planets (Rahu, Ketu, Saturn, Mars, Sun + lords of 6th/8th/12th houses), then scans every Dasha-Antardasha combination. KP house significations validate each window: divorce-triggering houses (1, 6, 10) and infidelity-triggering houses (5, 8, 12). Windows are further refined using D9 and D7 divisional chart validation. Result: a strategic timeline showing which years need extra care, with cruciality ratings for each period.
Predicts specific areas of friction before they happen. Categorized into four zones: People (in-law boundary challenges from malefic planets in 8th house overlays, Nadi Dosha family friction), Things (financial disputes from Mars/Saturn in 2nd house overlays, shared resource conflicts), Ideology (religious/political clashes from 9th house afflictions, philosophical differences), and Behavior (lifestyle and habit conflicts from 1st/6th house overlays). Each trigger is attributed to a specific partner's chart so you know who brings what energy.
Analyzes birth chart indicators for depression risk (Moon affliction, 4th house distress), anxiety tendency (Mercury-Rahu, Moon-Saturn aspects), emotional stability (Moon strength, 4th lord dignity), and stress resilience (Saturn's placement and aspects). Addiction risk covers five categories: sex addiction (Venus-Mars-Rahu patterns), alcohol/substance (Rahu-Moon, Neptune influence), drug vulnerability, compulsive behaviors, and Western outer-planet indicators — with protective factors (strong Jupiter, Saturn discipline) scored separately. Each category has its own risk score (0-100) and severity level.
Analyzes pre-marital history indicators (5th house patterns), affair context triggers, approach/capacity patterns, and spouse longevity assessment. Identifies narrative patterns like serial relationships, sudden attraction-repulsion cycles, and karmic relationship loops — with counterbalance factors and advice.
Bridges classical Vedic methods with modern psychological frameworks: Attachment theory mapping (secure/anxious/avoidant/disorganized per partner based on Moon, Venus, Saturn placements), shadow dynamics (unconscious relationship patterns from Rahu-Ketu axis), and outer planet cross-chart aspects (conjunction, trine, square, opposition with orb calculations) — blending Western astrology's psychological depth with Vedic precision.
Most Kundali matching tools use only Parashari (Ashtakoot Milan). Astro Marriage combines four distinct Vedic systems plus modern Western elements for cross-validated accuracy:
Each Nakshatra is divided into 9 unequal sub-divisions based on Vimshottari Dasha proportions, creating a 249-point zodiac map. The 7th Cuspal Sub Lord (CSL) determines if marriage is promised in the chart. If the 7th CSL signifies houses 2, 7, and 11, marriage is strongly indicated. The 4-fold significator chain (Planet → Star lord → Sub lord → Sign lord) provides timing precision no other system matches. KP Ruling Planets narrow marriage timing to specific months.
Uses Darakaraka (the planet with the lowest degree in the chart) as the primary spouse significator — its sign, Nakshatra, and Navamsa placement describe the spouse's nature, appearance, and profession. Upapada Lagna (calculated from 12th house lord's position) reveals marriage stability and family type. Jaimini Chara Dasha provides sign-based timing, and Vivah Saham (marriage sensitive point) activates during marriage-triggering transits.
Goes beyond basic Rashi (D1) chart with 16 divisional charts calculated using classical formulas: Navamsa (D9 — the marriage chart, most critical for compatibility), Hora (D2 — wealth), Drekkana (D3 — siblings/courage), Chaturthamsa (D4 — property/security), Saptamsa (D7 — children/progeny), Dasamsa (D10 — career impact on marriage), Dwadasamsa (D12 — parents), Shodashamsa (D16 — vehicles/luxuries), Vimsamsa (D20 — spiritual life), Chaturvimshamsha (D24 — education), Saptavimsamsa (D27 — physical vitality), Trimsamsa (D30 — misfortunes), Khavedamsa (D40), Akshavedamsa (D45), and Shashtiamsa (D60 — past life karma). The D9 Navamsa chart is used extensively for marriage compatibility validation and D9-to-D9 partner overlay analysis.
In addition to the North Indian Ashtakoot Milan (8 Kootas, 36 points), the app also calculates the South Indian 10 Porutham system used in Tamil Nadu and Kerala: Dina (star compatibility), Gana (temperament), Mahendra (prosperity/progeny), Stree Deergha (wife's welfare), Yoni (sexual compatibility), Rashi (emotional harmony), Rasiyathipathi (planetary friendship), Vasya (mutual attraction), Rajju (marital longevity — the most critical Porutham), and Vedha (affliction check).
Add multiple potential partners and the AI Matchmaking Engine ranks them across all 19+ analysis dimensions with a weighted scoring system: Risk Profile (35%), Dosha Analysis (20%), Ashtakoot (12%), Sexual Compatibility (10%), Psychological (8%), Extended Analysis (7%), Timing (5%), Remedies (3%). Each partner gets an overall score, category-wise breakdown, strength areas, challenge areas with mitigation strategies, and a comparison percentile ranking. The AstroMind AI chatbot (powered by Google Gemini) answers personalized questions about your chart in real time.
Kundali matching, also known as Gun Milan or Ashtakoot Milan, is a Vedic astrology method that compares two birth charts to assess marriage compatibility. It scores 8 aspects (gunas) across 36 points covering temperament (Varna), dominance (Vashya), destiny (Tara), sexual compatibility (Yoni), mental compatibility (Graha Maitri), nature (Gana), health/wealth (Bhakoot), and genetic compatibility (Nadi).
In Ashtakoot Milan, a score of 18 or above out of 36 is considered acceptable for marriage. Scores above 24 are good, and above 30 is excellent. However, overall compatibility also depends on Mangal Dosha status, Nadi Dosha cancellation, synastry aspects, and timing alignment.
Vedic astrology uses multiple systems to predict favorable marriage periods. The Vimshottari Dasha system (120-year planetary cycle) identifies when Venus, the 7th house lord, or Jupiter are active. Jupiter-Saturn transits over marriage houses open windows. KP Astrology's sub-lord system can narrow timing to specific months. When 3+ methods converge, the prediction confidence is highest.
Mangal Dosha (Kuja Dosha) occurs when Mars is placed in the 1st, 4th, 7th, 8th, or 12th house from the Ascendant, Moon, or Venus. While ~40% of people have some form, 15+ cancellation rules exist — Mars in own sign, Mars exalted, Jupiter aspecting Mars, both partners being Manglik, and many more. After applying all rules, only ~10-15% have truly active dosha.
Astro Marriage combines 4 Vedic systems (Parashari, KP, Jaimini, Bhrigu Nandi Nadi) instead of just basic Ashtakoot matching. It provides AI-generated insights, spouse prediction using Darakaraka analysis, multi-system marriage timing convergence, 15+ Mangal Dosha cancellation rules, sexual compatibility analysis, divorce/infidelity risk assessment, psychological profiling, and a partner comparison tool — all using Swiss Ephemeris (JPL DE431 accuracy) running entirely in your browser.
Yes, Astro Marriage is completely free. You can generate birth charts, check marriage compatibility using Ashtakoot Milan, get marriage timing predictions, compare multiple partner charts, and receive AI-powered insights at no cost. No sign-up is required for basic analysis.
Yes. All astrological calculations run client-side in your browser using Swiss Ephemeris compiled to WebAssembly. Your birth data is never sent to any server for calculations. If you create an account to save reports, data is stored securely in Supabase with encryption.
Yes. The Risk Radar module analyzes 12+ classical divorce indicators — 7th lord in dusthana houses (6th, 8th, 12th), separative planets in 7th house, 2nd house Mangalya Bhava affliction, 6th/8th lord entering 7th house, debilitated 7th lord, Venus affliction, and Mars-Saturn conjunction in 7th house. A protective buffer (Jupiter aspects, strong 7th lord, benefic influences) is deducted from the raw score. The result is a 0-100 probability with a level classification: low, medium, high, or very high. No other free Kundali matching tool provides quantified divorce risk.
Yes, in depth. The Sexual Compatibility module uses the 14 Yoni animal system with a full 14x14 compatibility matrix to assess physical chemistry and intimate compatibility between partners. Additionally, the Sexual Health module provides individual health indicators: for males, PME risk (Venus-Mars conjunction, Venus-Ketu conjunction, Mars in 7th/8th house) and ED risk (debilitated Sun, Saturn-Mars aspects); for females, frigidity and comfort indicators — with gemstone and lifestyle recommendations. Most competitors only show basic Yoni Koota score.
The Vulnerability Timeline is a lifetime scan that identifies exact years when your relationship faces maximum stress. It analyzes every Mahadasha-Antardasha combination involving risk planets (Rahu, Ketu, Saturn, Mars, Sun, plus lords of 6th/8th/12th houses) and validates each window using KP house significations and D9/D7 divisional charts. The result shows specific date ranges, cruciality ratings, and which partner's Dasha is triggering each period — helping you prepare for challenging phases in advance.
KP (Krishnamurti Paddhati) Astrology divides each Nakshatra into 9 unequal sub-divisions based on Vimshottari Dasha proportions, creating a 249-point zodiac map far more precise than the standard 27 Nakshatras. Astro Marriage uses the 7th Cuspal Sub Lord (CSL) to determine if marriage is promised in the chart. If the 7th CSL signifies houses 2, 7, and 11, marriage is strongly indicated. The 4-fold significator chain (Planet → Star lord → Sub lord → Sign lord) and KP Ruling Planets help narrow marriage timing to specific months. Most Kundali matching tools don't use KP at all.
Primarily Vedic, but it incorporates modern psychological frameworks. The Modern Insights module uses attachment theory mapping (secure/anxious/avoidant/disorganized), shadow dynamics analysis based on Rahu-Ketu axis, and outer planet cross-chart aspects (conjunctions, trines, squares, oppositions with orb calculations). It also includes addiction risk analysis using Western outer-planet indicators alongside Vedic combinations. This fusion provides psychological depth that pure Vedic tools lack.
