Looks very cool from a first glance! As it was mentioned in another comment, its hard to find a link to the source code of this, or even to get the information, whether this is open source, and what licence. (Answer: https://github.com/mu-editor/mu/, licence is GPLv3). For some people, this is some of the most important question before they would try out a new app. Also, one detail which was hard to find, but interesting for me: This is build using PyQt5. About the MacOSX package: It's about 430 MB. This is a lot for such a simple editor. Is this just because of PyQt5 which is bundled together with it? Isn't it possible to strip that down? I would have expected something like 5 MB or so. Also, another question: Is it possible to have this bundled into another existing app? E.g. I have an app where the user could write simple Python script

You go here: https://codewith.mu/en/developers Which links to here: https://mu.readthedocs.io/en/latest/ Which links to github (Watch button): https://github.com/mu-editor/mu/ I guess they didn't want "users" to accidentally think they need GitHub or read the "developer docs".

Here is the source, which strangely enough I don't think is linked from the website, unless I'm just missing it: https://github.com/mu-editor/mu
