Looks like a Huntsman Spider in the family Sparassidae.
is it Heteropoda venatoria?
What size is it (there’s nothing in the picture for scale)?
It looks a bit plain in pattern compared to H. venatoria I have seen. You are in pretty much the epicentre of Huntsman Spider diversity in India, with some 90+ species recorded in India, in several genera. There are over 20 Heteropoda species recorded in India so far.
