The next tool I want to review is Trinket. In my review of the other online IDEs, I didn't catch Trinket, but it ended up being the default that we will use in my classroom. It's another web-based IDE and in fact, the one recommended by TEALS. It again offers browser-based coding with in-page running as well as a terminal for straight python:
It offers a decent set of languages:
However, this language selection list highlights its biggest flaw. The free version limits saved languages to ones without the green key. I am teaching Python 3, and not being able to save trinkets basically almost makes the site useless for my teacher. I realize they want to make money, and I have no problem limiting functionality but stopping all saving of code for certain languages takes it a little too far.
One good feature, it does strongly support embedding in other web pages, so it looks strong for virtual textbooks. However, I cannot recommend it over https://repl.it/.
