For the work I do, I use - SBCL as the compiler - Emacs and SLIME for the editor/IDE - Quicklisp for package management - SBCL’s built-in static executable compiler for deployment, or sometimes docker if that happens to be more convenient - Practical Common Lisp for training; Paradigms in AI Programming for taking a trained Lisp programmer “minting” a better Lisp programmer For individual libraries, there are too many to name. I like yason for JSON, Hunchentoot for web servers, Postmodern for Postgres/SQL, cl-sqlite for SQLite, fiasco for testing, etc.
