JupyterLab

JupyterLab provides a web‑based interface for creating and editing computational notebooks, terminals, text files, and other assets in a single, flexible workspace. It builds on the Jupyter Notebook architecture, allowing users to combine code, narrative text, data, and rich visualizations—including 3D models and interactive controls—within shareable documents that support reproducible research and prototyping.

The environment is designed for developers, data scientists, educators, and researchers who need an extensible platform for interactive computing. It can be installed locally via conda, mamba, or pip, and runs on standard Unix‑like systems as well as Windows. Extensions written in npm can be added through PyPI, conda, or direct npm installation, enabling custom functionality and integration with other tools.

JupyterLab is open‑source under a BSD‑3‑Clause license, self‑hostable, and free to use without subscription. It includes features such as real‑time collaboration, debugger support, language‑server protocol integration, and a rich plugin system, and it is maintained as a stable, community‑driven project within the broader Project Jupyter ecosystem.
