- SBCL: Threading and AMD64 ports. Previously also Alpha and PPC ports, the contrib system, and random other stuff mostly pertaining to low-level and backend stuff. See the SBCL Internals CLiki site
- Araneida: the web server this all runs on
- asdf: A System Definition Facility
- detachtty: run persistent CL (or any other) processes in a detachable way, reattach to them using ssh across the network
