CodeSkulptor3 vs Pyto

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.

Pyto is an IDE for running Python 3.10 and C/C++ on iPhone and iPad. Its site says Python, clang, and an LLVM bitcode interpreter run locally on those devices. The editor offers syntax highlighting and code completion, while its terminal runs UNIX commands and scripts. Included libraries include NumPy, Matplotlib, Pandas, Statsmodels, SciPy, scikit-learn, scikit-image, and OpenCV. Pyto provides a traceback interface for debugging exceptions and an integrated file browser for projects; C/C++ programs can use setuptools or build_cproj. Python modules can be installed from PyPI. It can run scripts or custom code with Shortcuts and create Home Screen widgets. A free download is available with in-app purchases, and a 3-day trial is listed. Lite Version costs 7.99 USD once and unlocks Pyto without third-party libraries; Full Version costs 14.99 USD once and includes them. Mac support requires macOS 11 or later and Apple M1 or later.
