For a long, long time, it was accepted that programming languages couldn’t be simultaneously programmer-friendly and efficient. In 2011, we set out to prove that assumption was wrong. Crystal is the result of that experiment, and the source of much joy, fun and growth for everyone involved.

With thousands of contributions from people worldwide, it was finally possible to reach the level of maturity required for a 1.0 milestone.

And that calls for celebration!

The Crystal Conference will be livestreamed, to make sure that the entire global community that has formed around Crystal can attend.

Guest speakers in the conference include:

Carl Hörberg, CEO at 84codes, a Swedish tech company dedicated to simplifying cloud infrastructure for developers, and long time contributor to the Crystal project.

Ary Borenszweig, original creator of Crystal, and ever since member of the Core Team.

Bruce Perens, creator of the Open Source definition and co-founder of the Open Source Initiative, who has been working on the internationalization of Crystal.

Isaac Sloan, Chief Software Architect at Nikola Motors, a hydrogen-powered truck manufacturer and one of the largest contributors to the language.
