Create simple demonstrations for your programs
Elody allows you to create a link like this one, which anyone can click to quickly test your programs online. Just follow the link, then press the start button at the bottom. You can also make a link like this one, which will start automatically.
This allows you to easily demonstrate any software you write to other people online, without requiring them to download or install anything.
You can post that link on your github, or send it to people who you want to take a look at your programs.
Creating such a link does not take long and it works for any programming language that is supported by Docker.
To learn how to do it, read the tutorial up to this page, which shows how to do it on an example.
