How do you check your own openings

As the title says, I'd like to go over my openings and see were I go wrong and where I go right.

For the life of my I cannot find how to do it and google search returns just how to study opening in general and not go thorough your own games.

Thanks for reading

Use the lichess master database and watch youtube videos to learn openings for free. You can save the moves on a lichess study and review them. When you play a game, compare the opening to what you have in the study to see if you played the correct moves or not.

The website openingtree allows you to search through your games (all you have to do is enter a chess.com or lichess username) and see which moves you play the most commonly in certain positions.
