 * Perform processing and visualization tasks without needing a local Python environment;
 * Facilitate **collaborative data analysis**, sharing sessions or results with colleagues;
 * Integrate with JupyterHub, dashboards, or lab management tools for centralized usage.

+> ℹ️ The web frontend shall not replace the desktop application, but rather complement it by providing a different access mode. DataLab's philosophy is to remain a **local application** that does not require a server to run, ensuring data privacy and security. More precisely, the web frontend will empower users to run DataLab on a server and access it remotely - typically on a local network, but it will not be a cloud-based solution or a first step towards a fully cloud-based application which would be against the project's philosophy.
