CodeSkulptor3 vs NINJA-IDE

CodeSkulptor3 is a browser-based Python interpreter created for teaching Python, especially to beginners. The interface includes an editor and a console that displays printed output and error messages. It implements a subset of Python 3 and adds the SimpleGui, SimpleMap, and SimplePlot graphical libraries. The tool is featured in Coursera’s “Fundamentals of Computing” course, and the maker credits Scott Rixner with building it. Users can save programs to cloud storage under a URL or download saved programs to a computer. Anyone with a saved program’s URL can access its associated file. Collaborative editing sessions can be created or joined, but they are temporary and deleted in about a day. Modern Google Chrome, Mozilla Firefox, and Apple Safari are listed as supported browsers. The documented Python subset excludes constructs including try-except and with statements. Programs can load external files only over HTTPS. The maker says users are anonymous and personal information is not collected. Saved files are stored indefinitely and used to provide the service and anonymous educational research.

NINJA-IDE is a free integrated development environment for creating applications, with tools for managing Python projects. The editor provides syntax highlighting, code completion, and help with imports and navigation. A code locator gives access to project files, functions, and classes, and documents can highlight static and PEP 8 errors. Users can manage files within the IDE, run a Python project or open file with one click, and render HTML files inside the application. Plugins can extend the editor and integrate functionality. The download page lists v2.4 installers for Windows 10/11 and Linux distributions; its macOS entry says the app is unavailable there and offers source code only. Listed requirements are Python 2.7 and PyQt 4.7 or later. The project describes the software as GPLv3+ and lists a mailing list and GitHub issues for questions and bug reports. The website says it is no longer run by the official authors.
