JupyterLab is a web-based, extensible interactive computing environment built on the Jupyter architecture. It provides a unified workspace for authoring and running notebooks, editing files, using terminals, and exploring data with rich, interactive outputs.

Key Features

• Multi-document interface combining notebooks, text editor, terminals, file browser, and rich outputs in one workspace
• Extension system for adding UI panels, commands, renderers, and integrations (prebuilt and source extensions)
• Notebook authoring with executable cells, embedded narrative text, and rich visualizations
• Kernel management for running code in different languages via the Jupyter kernel protocol
• Workspaces and customizable UI layout, settings, and keyboard shortcuts
• Real-time collaboration support (when configured with compatible server components)

Use Cases

• Data exploration and visualization workflows for analytics and research
• Reproducible reports and computational narratives shared as notebooks
• Teaching, workshops, and interactive coding environments for teams

Limitations and Considerations

• Advanced capabilities (for example real-time collaboration and multi-user deployments) may require additional configuration and compatible backends such as Jupyter Server/JupyterHub
• JupyterLab 3 has reached end of maintenance; newer deployments should use JupyterLab 4

JupyterLab is a flexible choice for individuals and organizations that need an interactive, browser-based environment for notebooks and code. Its modular architecture and extension ecosystem make it suitable for both lightweight personal use and more customized, integrated deployments.

RStudio Server is a web-accessible version of the RStudio IDE for data science development in R and Python. It provides a full coding workbench in the browser, making it easier to centralize compute and enable access for multiple users.

Key Features

• Browser-based IDE experience with console, source editor, plots, workspace, help, and history
• Syntax highlighting, code completion, and smart indentation
• Run code directly from the editor (line, selection, or file)
• Project-based workflow for managing multiple working directories
• Integrated tools for debugging and error diagnosis
• Authoring support for technical documents, including Sweave and TeX
• Package development tooling to support R package workflows

Use Cases

• Centralized data science environment for teams using shared servers or managed infrastructure
• Teaching and training environments where learners access a consistent IDE via a browser
• Remote development when local installation is not desired or practical

RStudio Server is a mature, widely used IDE option for organizations standardizing R/Python workflows and offering a consistent development experience across users and machines.
