Everyone says “Nobody uses Lisp” and Lispers say “Yes they do, there’s ITA, and, um, Autocad, and, uh, oh yeah, Paul Graham wrote Viaweb in Lisp!” Not very helpful for either side.
Following Lisp Companies blog post (2008, many dead links).
Of course, see
- lisp-lang.org’s success stories for a showcase of projects and companies in aerospace, AI & Machine Learning, Science, Graphics etc.
- franz.com success stories
- lisp-journey’s short software list (pgloader,…)
- awesome-cl-software (old and current),
- awesome-cl libraries.
- awesome-lisp-companies, a bigger list.
Let’s quote Kent Pitman’s famous answer:
But please don’t assume this is an exhaustive list, and please don’t assume Lisp is only useful for Animation and Graphics, AI, Bioinformatics, B2B and Ecommerce, Data Mining, EDA/Semiconductor applications, Expert Systems, Finance, Intelligent Agents, Knowledge Management, Mechanical CAD, Modeling and Simulation, Natural Language, Optimization, Research, Risk Analysis, Scheduling, Telecom, and Web Authoring just because these are the only things they happened to list. Common Lisp really is a general language capable of a lot more than these few incidental application areas, even if this web page doesn’t totally bring that out.
(and this list doesn’t mention that it was used for auto-piloting the DS1 spaceship by the NASA for several days)
