Anvil vs Pydroid 3

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.

Pydroid 3 is an educational Python 3 IDE for Android. Its interpreter runs programs without an internet connection, and pip connects to a repository of prebuilt wheels including NumPy, SciPy, Matplotlib, scikit-learn, and Jupyter. The listing also names OpenCV, TensorFlow, PyTorch, Tkinter, Kivy, PySide6, and pygame support; OpenCV needs Camera2 API support. C, C++, and Fortran compilers are included, with Cython support. A PDB debugger provides breakpoints and watches. The editor has syntax highlighting, themes, tabs, an extended keyboard bar, and code navigation. Code prediction, auto-indentation, and real-time code analysis are Premium-only. The free plan is ad-supported and excludes Premium-only features and libraries. Pydroid 3 requires at least 250 MB of free internal storage, with 300 MB recommended. Its privacy policy describes crash and package statistics collection and use of several third-party services.
