Common Lisp libraries
Where to find them, and where they are installed from.
These are the distributions Common Lisp libraries are installed from, and the directories and references that the community keeps of them. Start with any of them to find a library for the job at hand.
The most recently updated source is listed first. Every six hours the site asks each one when it last changed (a distribution's latest release, a repository's last push, a page's own date) and sorts by that day. A source that publishes no date a program can read comes after the others, by name.
Awesome Common LispDirectory, last changed
A list of libraries by area, kept by its contributors on GitHub, with marks on the ones they consider the usual choice. The list this page carried until October 2026 was a copy of it.
UltralispDistribution, last changed
A second distribution for the Quicklisp client, rebuilt from its projects' repositories as they change, and open to any project whose author adds it. Its front page is a search of what it holds.
ociclDistribution, last changed
A library manager that keeps each project's libraries with the project, fetched as OCI artifacts from a container registry and recorded in a file of versions.
CLikiDirectory, last changed
The Common Lisp wiki: pages on libraries by topic, written and corrected by whoever knows. Current recommended libraries is its own short list.
QuickrefReference, last changed
A reference manual for every library in Quicklisp, generated from the code itself: its systems, files, packages and definitions.
QuicklispDistribution, last changed
A library manager and its distribution: some 1,500 projects, released together after they have been built together.
(ql:quickload "name")fetches a library and everything it needs. Its releases page lists every project in it.portability.clReference, publishes no date
Which implementations each portability library supports, as tables.
QuickdocsReference, publishes no date
A search of the libraries in Quicklisp, with each one's README, dependencies and download figures.
Projects hosted here
Many libraries have their repository on this site's GitLab. The projects hub lists them, and the GitLab itself can be searched and sorted by activity.
The list that was here
Until October 2026 this page was a long list of individual libraries, taken from Awesome Common Lisp and last brought up to date with it in 2020. It is still on the old site, as it was. To have a source added to this page, or one corrected, use the link below: an entry needs an address and one sentence that says what it is.
