Chess
in a link.
Make your move. Copy the link. Send it to your mate. They open it, see your board, play their move — the whole game travels inside the URL.
Three taps. One link. A whole game.
chextmate is a single-file chess app that doesn't need a server. Everything required to continue the game — position, last move, whose turn — is encoded right there in the link you share.
Make your move
Tap a piece, tap where it should go. The board enforces legal moves, handles promotions, calls out check.
Copy the link
The URL updates after every move. One tap puts the entire game on your clipboard, ready to share.
Send it anywhere
iMessage, email, Discord, a sticky note in Notion. They open it and see the exact board you saw.
Most chess apps need accounts, push notifications,
and a server somewhere keeping score.
chextmate doesn't.
Built around one strange idea.
No rush, no clock
Play a move over coffee. Reply tomorrow. The game waits in the link until someone opens it.
Nothing to sign up for
No email, no password, no profile. There's no database to leak because there's no database at all.
Works on anything with a browser
Phone, laptop, the weird tablet in your kitchen. It's one HTML file behind a chess engine.
The URL is the save file
Bookmark it, paste it into a doc, print it out. As long as you have the link, the game is alive.
