ChessLM: a full web chess platform in Next.js

My own product, live and free, and still in active development. Players can play the computer with Stockfish running in the browser, join a rated or casual queue with Glicko-2 ratings and public profiles, or challenge friends. It also has 18+ variants, a large puzzle library with daily and timed modes, and a 28-step learning curriculum with endgame and coordinate drills. Accounts sync games across devices, and games export as PGN. I built the product end to end, including the real-time multiplayer and rating logic. Stack: Next.js, TypeScript, shadcn/ui, Convex, Clerk, Vercel.
