About


Crystal is a programming language with the following goals:

  • Have a syntax similar to Ruby (but compatibility with it is not a goal).
  • Be statically type-checked, but without having to specify the type of variables or method arguments.
  • Be able to call C code by writing bindings to it in Crystal.
  • Have compile-time evaluation and generation of code, to avoid boilerplate code.
  • Compile to efficient native code.
