The anywidget project provides a specification and toolset for creating portable web-based widgets for computational notebooks. It defines a standard for front-end widget code using ECMAScript modules and offers tools for authoring, distributing, and executing these modules across Jupyter-compatible platforms (e.g., JupyterLab, Google Colab, VS Code). The project has spurred the creation of many interactive visualization libraries and has been integrated into existing ones. The standard has been embraced by other notebook platforms and web frameworks, extending the reach of interactive widgets beyond the Jupyter ecosystem.
