As answered by people managing Fly.io and ILoveDevTool Python Playground.
ILoveDevTool Python Playground's answer:
Pyodide (WebAssembly), Next.js, React, CodeMirror and Tailwind CSS.
ILoveDevTool Python Playground's answer:
Your code runs 100% in your browser via Pyodide (CPython compiled to WebAssembly) — nothing is sent to a server. It still supports NumPy, Pandas, Matplotlib, Scikit-learn and Requests, plus installing pure-Python PyPI packages with micropip and uploading your own modules.
ILoveDevTool Python Playground's answer:
Free, no sign-up, and private by design: code and data never leave your device. It works with interactive input(), plots Matplotlib charts inline, and the UI is available in 20 languages.
ILoveDevTool Python Playground's answer:
Students learning Python, teachers running classroom exercises, and developers who want to quickly test a snippet or a data-analysis idea without installing Python locally.
ILoveDevTool Python Playground's answer:
ilovedevtool started as a collection of free, privacy-friendly developer tools. The Python compiler was built to give learners a zero-setup way to run real Python, including the scientific stack, directly in the browser.
