There are now 300 languages posted here… Ok, 68 broken links are reported but still there is a lot to explore about programming language implementations. Thanks to everyone who contributed so far!
The site now has a much better structure making each language a post of its own. So you can comment on each and every language and updates on pages are replaced with the posting of new articles. The navigation now is via tags which are already now richer than the old “pages” structure. There are some remaining minor issues left. There are now 286 posts on languages. My new broken-link checker reports about 64 broken links.
I hope you find this more useful now.
This site is no longer maintained, you see a static version as of March 18, 2018. I expect links to break.
For comments and corrections, or to propose something to be included in the list, please send a mail. I do not take any guarantee about the quality of software referenced here. Use at your own risk. I want to say thank you to all those people that pointed me to new systems to include here. It is amazing that not only the authors themselves help to keep this list as complete as possible, but also people that come across something interesting.
