For matching of horoscopes, you will have to come through paid services. Read my articles on this site to understand matching of horoscopes scientifically. There is also an article of Nadi dosha too and remedies available.

Nadi Dosha, is one of the most important factors in Kundli Milan. It can create concerns about health, compatibility, and childbirth, but there are few remedies to reduce that can reduce its impact. The simplest remedy is performing a Nadi Dosha Nivaran Puja by a karamkand brahmin.

In the birth charts of boy and girl If the dosha appears but the couple has the same rashi but different nakshatra padas then Nadi dosha can be ignored. Also, check Nadi Paad vedha to be sure that Nadi dosha gets cancelled.

Mantras like the Mahamrityunjaya Mantra strengthen marital harmony and reduce Nadi dosha impact; however, it has to be done as per instructions given in the shastras.
