What PyBox is
PyBox is a free, open-source Python development environment that runs in a browser. Its editor offers syntax highlighting and intelligent autocompletion for writing and running code. A file explorer supports drag-and-drop, file and directory uploads, renaming, deletion, and ZIP export of projects. The built-in package manager installs Python packages and displays the installed list. PyBox also includes an interactive Python console with real-time commands, history, tab completion, and a filesystem synchronized with the editor. It can render Matplotlib plots and display HTML, images, SVGs, and styled text in a visual container. An experimental Bash terminal uses Wasmer and is described as virtualized for secure execution. The project uses Pyodide and Wasmer and is licensed under MIT. Local setup requires Node.js 14 or newer plus Yarn or npm. Planned work includes collaboration, more languages, improved debugging, and Git integration.
