pgloader is a data migration tool designed to load data into PostgreSQL from various sources. It automates the process of migrating databases, handling schema transformations and data type conversions. pgloader supports high-speed data loading using PostgreSQL's COPY command and provides detailed logs for monitoring the migration process.

Steel Bank Common Lisp (SBCL) is a high-performance Common Lisp compiler. It is open-source/free software, with a permissive license. In addition to the compiler and runtime system for ANSI Common Lisp, it provides an interactive environment including a debugger, a statistical profiler, a code coverage tool, and many other extensions. SBCL runs on Linux, various BSDs, macOS, Solaris, and Windows. See the download page for supported platforms, and the getting started guide for additional help. SBCL is available in source and binary form for a number of different architectures. SBCL is available in binary form for many architectures. To obtain the latest binary release for your system, visit the platform support page and click on the green square which indicates your platform. You can install SBCL to a different directory prefix by setting the INSTALL_ROOT environment variable before running the installation script.

Out of the box Nyxt ships with tens of features that allow you to quickly analyze, navigate, and extract information from the Internet. Plus, Nyxt is fully hackable- all of its source code can be introspected, modified, and tweaked to your exact specification. Navigate large documents with ease. Utilize the power of running commands against multiple objects to avoid repeating yourself. You can select and close all buffers that match the string "ele". Fuzzy search-relevant commands to instantly run them. No more digging through menus. Use fuzzy search to instantly switch between buffers. No more hunting! Use link hinting to quickly jump around. Jump to a link by URL, title, or shortcut. Use the built-in REPL to program Nyxt. Run short scripts, and try out new workflows. Everything in Nyxt is fully extensible and modifiable. Smart bookmark search.

Trial is a real-time, 3D game engine written in Common Lisp, offering a modern and modular approach to game development using the expressive power of Lisp. Built on top of the cepl graphics framework, Trial combines live-coding capabilities with powerful abstractions for building simulations, scenes, and interactive applications. It emphasizes flexibility, clarity, and developer control, making it an appealing choice for experimental games, visualizations, and research projects that benefit from dynamic development environments and rapid prototyping.

Qlot is a project-local library installer for Common Lisp, utilizing the Quicklisp facility. It enables developers to manage dependencies on a per-project basis, ensuring consistent environments and avoiding conflicts between projects. Qlot is akin to Bundler for Ruby or Carton for Perl, providing a familiar experience for developers from other ecosystems.​

Lisp Koans is a self-guided learning path for Common Lisp that teaches the language’s idioms through a series of failing tests you progressively make pass. Each koan introduces a concept—symbols, lists, macros, multiple dispatch, reader syntax—then asks you to fill in the blanks and run the suite again. The feedback loop is intentionally tight: fail, reflect, fix, and rerun until the tests become a form of living documentation. Because koans are organized from fundamentals to metaprogramming, learners internalize not just syntax but also Lisp’s philosophy of code-as-data. The exercise format makes it ideal for workshops, katas, or leveling up engineers who have never touched a Lisp before. It’s minimal on infrastructure and maximal on discovery, encouraging use of a REPL and inspector while you solve each puzzle.

Computer Music Programming Language

This project is dedicated to developing more readable format(s) for Lisp-based languages (such as Common Lisp and Scheme) and implementing those formats (readers, pretty-printers, editor macros, etc.). MIT license preferred, to spread them widely.

Garnet is a Graphical Toolkit for Lisp, which offers many advanced features. It was originally developed by Carnegie Mellon's User Interface Software Group and is one of the most feature rich interface toolkits available for lisp. The project has been dormant but some of us are trying to update it. To get the latest stable code, use the subversion repository: svn checkout svn://svn.code.sf.net/p/garnetlisp/svn/trunk garnetlisp-svn

The Common Lisp Reasoner extends the Common Lisp Object System (CLOS) to incorporate a powerful rule language suitable for all kinds of reasoning tasks, vanilla XML and RDF/XML interfaces, and support for a variety of AI-related applications, such as scheduling, planning and diagnosis.

GTK2 binding for common lisp, based on CFFI and CLOS

SNMP (Simple Network Management Protocol) for Common Lisp, UDP Networking for LispWorks, ...

Snow is a Lisp-based GUI description DSL for Swing. It supports declarative layout, data binding, event listeners implemented in Java or Lisp. NOTE: the project is now hosted on common-lisp.net.

Binary file format provides interface for Common Lisp to read and write binary files in a simple way.

Toolbox contains a few common utilities used in other projects. Toolbox has also for example a generic non-trivial double-linked list implementation which uses SBCL's weak-pointers when referencing to previous item.

droite is a correction of eS expression parsers implemented in many different programming languages. Its usefulness is the same as JSON but droite utilizes eS expression, a Gauche scheme interpreter friendly S expression variant.

Acheron is a Common Lisp (CL) to JavaScript (JS) compiler. Programs are written in a subset of CL and after compilation executed in a webbrowser. Acheron has native functions that are written in JS and are the bridge between CL and JS.

Compiler of Lisp programs to a platform-idependent bytecode and the corresponding virtual machine.

A general and small implementation of an artificial neural network in Common Lisp.

Hard disk forensics in the lisp way.

cl-pcp is a collection of Common Lisp CFFI bindings for Pango, Cairo, and PixBuf from the GTK+ (Gimp Tool Kit) Project. This is meant as a lightweight, general solution for developing graphical/text based applications in Common Lisp.

CIOS Audio Core is the infrastructure and subsystem in Collective Intelligence Operation System. It is a cross platforms audio abstract interface, supports including Mac OS X, Linux, Android, iPhone OS and Windows 7.
