Python Online vs Pyto

Python Online is a browser-based, container-backed Python IDE for writing, running, and hosting applications. Code executes in isolated Linux containers, while the Monaco editor provides IntelliSense, multi-cursor editing, flexible pane layouts, and Ruff linting. Users can search PyPI and install packages in isolated project environments. Hosted Flask, FastAPI, Django, and Streamlit applications receive pythononline.app subdomains with SSL. Registered accounts can schedule one daily headless task limited to 60 seconds. A persistent Python REPL supports interactive work, and matplotlib or plotly plots can appear in the output console. The free registered account costs nothing and includes up to three projects, 512 MB cloud storage, one hibernating web app, one daily task, and proxy-based outbound access. Guest projects remain in browser memory and lack internet, hosting, and scheduling. Projects export as ZIP archives.

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.
