Velocitychess came to us with a goal of creating website that would allow to play blitz chess games between players from all around the world. Our solution had to support large traffic and be accessible from countries with poor internet brandwidth. It had to be compatible with mobile devices.

Website’s goal was to be a chess hub with social networking options, tutoring tools and gamification mechanics. This project was ambitious from the start.


We chose node.js as a technology to implement chess games. Along with MongoDB and Redis no-sql databases, as well as knockout and javascript on the frontend, it allowed us to create a solution that can support hundrets of games at once.

We avoided using flash or Java, which prevented competitive websites to run on mobile devices and require users to download applets. We decided to go with much nicer javascript solution.

For chess logic, we used Stockfish script and we adapted it to our needs. We created a set of chess bots with different skill levels, with which players can train before challenging live users.
