Any ideas about self hosted tools for trying out code snippets?
I could use something like the typical w3schools example site, but self hosted and ideally, with support for a couple of files simultaneously. For example, editing a HTML and CSS files, or web-framework script and the HTML template file.
The use case is, that I upload some examples and my students can experiment with them and see the output without altering the originals.
Is there something like that already available, or does it involve implementing it by yourself?
