365Chess is a possible database; although I don't know whether it requires payment. If this is something you don't like, you can Google "chess databases" and it will display various databases you could use.
Please DM (direct message) me if you need any more information.
Hello, everyone!
It's my first post here.
I would like to ask a question about databases. I know there is ChessBase, there is Chess.com library and LiChess allows you to create a repertoire. However, I was looking for a way to create a database offline, preferably for free. Do you have any knowledge on this and a suggestion to make?
Thanks for reading and your help.
Have a fantastic day!
