CodeSkulptor3 vs PyCharm

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.

PyCharm is an IDE for web, data, and AI/ML professionals, with tools for Python development. It provides code completion, PEP 8 checks, inspections, and refactoring, alongside debugging and testing. The IDE includes an integrated terminal, package managers, Docker integration, and support for Pipenv, conda, virtualenv, and Poetry. Version control includes Git, GitHub, GitLab, Subversion, Mercurial, and Perforce; database tools cover MySQL, SQL Server, PostgreSQL, Oracle, Redis, and other providers. Local AI code completion can run local LLMs without sending code over the internet. Remote development supports several listed services, and remote connections use end-to-end TLS 1.3 with SSH security and host-fingerprint verification. PyCharm runs on Linux, macOS, and Windows. Its free plan costs nothing and includes one month of Pro. The listed Pro plan costs $200 a year, billed per user per year. PyCharm Ultimate can be evaluated free for 30 days before purchase and license activation are required.
