Online chess, without the noise

One board. Two simple ways to play.

Chessdox is a free browser chess game built for a quick private match. Start immediately, choose your clock and color, and keep the focus on the board.

Play chess online with friends

Create a private room and send one secure invite link. Your friend joins directly in the browser—there is no account, public lobby, or installation.

Create a private game

Play chess against the computer

Choose from four strengths, pick your side, and play a complete legal game. The Chessdox computer runs on the server, so it works on phones, tablets, and desktops.

Challenge the computer

Private by design

Games are shared by a one-time invite instead of a public profile. Moves are validated by the server, and finished games can be downloaded as PGN.
