Steel Bank Common Lisp (SBCL) is a high-performance open-source compiler and runtime system for ANSI Common Lisp. It includes an interactive environment with a debugger, statistical profiler, code coverage tool, and many extensions.

Use cases

compile and run Common Lisp programs
interactive Lisp development with a REPL and debugger
profile and optimize high-performance Lisp applications
build cross-platform command-line tools in Common Lisp
learn or teach ANSI Common Lisp

When to choose

you need a fast, actively maintained Common Lisp implementation
you want a permissively licensed Lisp runtime across Linux, BSDs, macOS, and Windows
you need built-in debugging, profiling, and code coverage tooling

When to avoid

you need a different Lisp dialect such as Scheme or Clojure
you require a bytecode-only or very small-footprint Lisp runtime
you need a graphical IDE out of the box
