Anvil vs Pyzo

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.

Pyzo is a free, open-source Python IDE built for interactive and simple programming. It targets data-centric work including learning, science, data analysis, and application development. The editor provides auto-indentation, syntax highlighting, regular-expression search and replacement, and debugging breakpoints. Its shell can run code, selections, cells, or files, and multiple shells can operate simultaneously with different Python versions. Shells run in interruptible subprocesses. Session and source completion, function call tips, interactive help, a file browser, source structure view, workspace, and logger support development. Pyzo works with system-installed Python interpreters, including Conda environments, and supports pip or conda package management plus several GUI toolkits. It runs on Linux, macOS, and Windows. Running code requires installing both Pyzo and a Python environment.
