A deep dive into the world’s most popular open-source chess platform, its impact, and how you can be part of its future.

The Chess Revolution

In 2010, a programmer named Thibault Duplessis had a simple yet powerful vision: create a chess platform that would be completely free, open-source, and accessible to everyone. Today, that vision has evolved into Lichess (pronounced “lee-chess”), a platform that serves millions of players daily and hosts billions of games annually. The name itself reflects its technical roots: “lila” = lichess in Scala.

“Lichess started as a weekend project. I never imagined it would become what it is today – a platform that makes high-level chess accessible to everyone, everywhere.” - Thibault Duplessis, Lichess Founder
