ChessDream, a place for chess players to improve

It's clear domain knowledge is lacking in this project. Things like not numbering moves in engine lines, not naming the engine you are using, showing an eval from a point of view of a side to play (usual convetion is to show it from white's point of view so positive eval means better for white, negative eval means better for black) are giveaways. There are also bugs in the puzzle section. I encountered one that says black to move but only accepts white's move. Some end too quickly as well.

If you are looking for advice then I would recommend some humility and working on domain knowledge. It's a tough space to make a business in as there are very strong free services (like Lichess) and great commercial ones (like Chesstempo). Even making one thing better than Lichess might win you some users and potential customers but it won't happen by claiming it's already "quickly happening".

presumably this is equivalent to stockfish or leela, or AlphaZero. not saying what's "behind the curtain" => fail.

fwiw, lichess.org is free, stable, open source and uses strongest engines: stockfish, leela, and is free.

Are you using an opensource engine without specifying it?
