Anvil vs CodeSkulptor3

Anvil is an online IDE for building and deploying full-stack web apps with Python. It pairs a drag-and-drop interface designer with client-side and server-side Python, and includes Data Tables, a built-in database backed by Postgres. Apps can be published to Anvil hosting or exported to run on the open-source Anvil App Server. Developers can create HTTP APIs and connect external Python code through Uplink. Built-in user authentication and app email support cover sending and receiving messages. Anvil documentation lists integrations for Google, Microsoft Entra ID, Facebook, Stripe and Tableau, and says Python SDKs can connect other services. Apps adapt to phones and tablets; the FAQ describes them as installable Progressive Web Apps for Android, iPhone and Chromebook, with offline operation. The Free plan includes unlimited apps and cloud hosting, but provides 50,000 Data Table rows and 100 MB of Data Table storage. Anvil says its hosted infrastructure is in London on AWS eu-west-2. It also says its API removes common flaws such as injection, XSS and CSRF.

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.
