Compatibility

The Compatibility engine.

All compatibility endpoints in one cluster: 8-koot Gun Milan, 10-koot Dashakoot, Tamil-tradition Nakshatra + Thirumana Porutham, Western synastry / composite, Western zodiac quick-check, and Ank Milan numerology. Plus batch scoring for matrimony portals (up to 500 pairs per call), Papa Samyam malefic-balance for couples, and an async PDF compatibility report.

  • Ashtakoot Gun Milan with cancellation-aware koot scoring
  • Dashakoot (10-koot) variant for South Indian traditions
  • Porutham — both Nakshatra (Kerala-tradition) and Thirumana (Tamil-tradition marriage) variants
  • Western synastry + composite (chart + aspects for each)
  • Ank Milan numerology compatibility — three facets
  • Western sun-sign × sun-sign quick check
  • Batch scoring (up to 500 pairs/call) for matrimony-portal workflows
  • Papa Samyam couple malefic-balance + async detailed PDF report
