Crystal is fast as C and slick as Ruby. Crystal’s syntax is heavily inspired by Ruby’s, so it feels natural to read and easy to write, and has the added benefit of a lower learning curve for experienced Ruby devs. Crystal is statically type checked, so any type errors will be caught early by the compiler rather than fail on runtime. Moreover, and to keep the language clean, Crystal has built-in type inference, so most type annotations are unneeded.Besides commercial projects, we maintain several OpenSource repositories in Crystal: to us

Why we love Crystal

  • Crystal feature 1
    Crystal is a general-purpose, object-oriented programming language designed for building scalable and easy-to-maintain applications. It is based on LLVM and compiles to efficient native code. While having syntax very similar to Ruby, it can be used to build low-latency, distributed, and fault-tolerant systems while also being perfectly suited for web development.
  • Crystal feature 2
