Hi! I’m crufter. I am one of the first authors of this site, in fact as you can see I named it after myself, because I am way more egotistical than I should be. Enjoy.
crufter.com is a multi-author site for tutorials and articles. We support interactive code execution out of the browser, so your tutorial readers can learn without installing anything on their machine!
The website itself is completely open source, send a PR with improvements or your own content here.
