ChessApp – Search FIDE, Chess.com, and Lichess players and repertoire and map

Hi HN! I recently built ChessApp, a web application for over-the-board (OTB) chess players, but it’s also useful for anyone in the chess community.

Main features:

Player Search: Find any FIDE-registered player (1.5M+), or users from Chess.com and Lichess.

Repertoire Viewer: Enter a username and a color to view their opening repertoire.

Chess Map: Discover places to play chess worldwide (DM me to suggest a new location).

Game Review: In development — will offer post-game analysis features.

I'm actively working on new features (like an Elo calculator, searching people by email, dark theme, etc.), and I'd love to hear your thoughts on the UI/UX, ideas for improvement, or general feedback!
