It's very good for CLI apps, and quick one programs, web dev is decent Lucky is an awesome framework, the compile times make the code-compile-reload cycle subpar, specially if you compare it to scripting languages. Performance is normally excellent but the GC is suboptimal for some workflows, it's not yet written in crystal and it's too conservative recouping memory. The nicest side effect of crystal is that it's programs are far more likely to work on first compiles than ruby scripts, and the type system makes refactoring a large code base much safer.
