user307: Inspired by this question What rules are known for Chaturanga?
Chaturanga seems quite interesting, and some aspects of it, like no castling are being introduced in other variants: Kramnik's chess. Given that, say, lichess.org has so many variants, is there a reason why Chaturanga is not of them?
Possible reasons:

The rules are not exactly known.

Queen (Mantri) is much less powerful and pawns don't have a 2-square move option on the first move, which makes the game less interesting / drawish to many people.

Strategies were developed to draw fairly easily, (and that's why rule changes were introduced). This is a stronger version of 2), and probably not likely.



user23100: You answered your own question, with 1) and 2) being the main causes!
I don't know about 3), tbh, but it seems at least somewhat plausible (although stalemate was also a win in chaturanga so who knows!).
You say that it's not on main chess sites, but chess.com at least has it as a playable variant- can't speak for how easily you'll find a game there however.
It's also presumably not trivial to code the game, which is probably another reason why.
