Executes code cells individually against a Jupyter kernel process running in a separate process or remote environment, communicating via the Jupyter Wire Protocol. Each cell maintains execution state in the kernel, enabling incremental development workflows where variables persist across cell runs. The extension marshals code from the notebook editor to the kernel, captures stdout/stderr, and returns execution results without requiring full script re-execution.
Unique: Integrates Jupyter kernel execution directly into VS Code's native notebook editor (not a separate UI), leveraging VS Code's built-in notebook infrastructure rather than embedding a custom notebook renderer. This allows seamless integration with VS Code's file system, command palette, and settings while maintaining full Jupyter protocol compatibility.
vs alternatives: Tighter VS Code integration than JupyterLab (no context switching) and lower overhead than running standalone Jupyter, but depends on external kernel installation unlike some cloud-based notebook platforms.
Renders cell execution outputs by detecting MIME types (text/plain, text/html, image/png, application/json, text/latex, application/vnd.plotly.v1+json, etc.) and delegating to specialized renderers. The Jupyter Notebook Renderers extension (auto-installed) provides built-in renderers for common types; custom renderers can be registered via the Notebook Renderer API. Output is displayed inline below the cell with support for interactive elements (Plotly charts, HTML widgets).
Unique: Uses VS Code's native Notebook Renderer API to register MIME type handlers, allowing third-party extensions to contribute custom renderers without modifying the core extension. This architecture mirrors VS Code's extension ecosystem model and enables community-driven renderer development.
vs alternatives: More extensible than JupyterLab's fixed renderer set and better integrated with VS Code's extension marketplace, but requires extension development for custom types vs JupyterLab's simpler plugin system.
Allows connecting to Jupyter kernels running on remote servers or cloud platforms via SSH, HTTP, or cloud-specific endpoints. Users can configure remote kernel connections in VS Code settings or via the kernel picker UI, specifying connection details (host, port, authentication). The extension communicates with remote kernels using the Jupyter Wire Protocol over the network, enabling execution of code on remote compute resources without local installation. Supports GitHub Codespaces kernels and custom remote kernel servers.
Unique: Supports both SSH and HTTP remote kernel connections, enabling flexibility in deployment scenarios (on-premises servers, cloud VMs, managed Jupyter services). GitHub Codespaces integration allows seamless kernel access in browser-based VS Code without local setup.
vs alternatives: More flexible than JupyterLab's remote kernel support (supports multiple connection types) and enables cloud compute without leaving VS Code, but requires manual configuration vs some platforms with built-in cloud provider integrations.
Stores notebook-level metadata (kernel name, language, custom settings) in the .ipynb file's 'metadata' JSON object. When a notebook is opened, the extension reads the stored kernel name and automatically selects that kernel, ensuring consistent execution environment across sessions. Users can also configure kernel-specific settings (e.g., Python environment variables, kernel arguments) in the notebook metadata or VS Code settings. Metadata is preserved when notebooks are shared or version-controlled.
Unique: Stores kernel metadata in the standard .ipynb format, ensuring compatibility with other Jupyter tools and version control systems. Automatic kernel selection based on metadata reduces manual configuration when opening notebooks.
vs alternatives: Ensures reproducibility by storing kernel information with the notebook, but requires manual kernel installation vs some platforms with built-in environment provisioning.
Exports notebooks to multiple formats (HTML, PDF, Markdown, Python script) using nbconvert integration. Triggered via command palette (`Jupyter: Export as...`) or right-click context menu. Requires nbconvert package and optional dependencies (pandoc for PDF, etc.) to be installed in the kernel environment. Exports preserve cell outputs, metadata, and formatting based on the target format.
Unique: Integrates nbconvert directly into VS Code's command palette and context menu, providing one-click export without requiring command-line usage, while maintaining full compatibility with nbconvert's format options.
vs alternatives: More convenient than command-line nbconvert because it provides a UI-based export workflow, while maintaining full feature parity with nbconvert's conversion capabilities.
Displays a panel showing all variables currently defined in the kernel's namespace, including their type, shape (for arrays/DataFrames), and value. The extension queries the kernel using introspection commands (e.g., Python's dir() and type() functions) to populate the variable list. Clicking a variable can show its full representation or open a data viewer for large structures like DataFrames. The variable list updates after each cell execution.
Unique: Integrates variable inspection into VS Code's sidebar as a native panel (not a separate window), providing persistent visibility of kernel state alongside code and output. Uses kernel introspection rather than static analysis, ensuring accuracy for dynamically-typed languages.
vs alternatives: More integrated into the editor workflow than JupyterLab's variable inspector (always visible in sidebar) and faster than manually printing variables, but less detailed than specialized data profiling tools like pandas-profiling.
Provides UI for discovering, selecting, and switching between Jupyter kernels installed on the system or accessible remotely. The kernel picker (dropdown in notebook toolbar) queries the system for available kernelspecs (JSON files defining kernel metadata and launch commands) and allows users to select one. Switching kernels restarts the kernel process and clears the previous kernel's state. The extension can also auto-detect Python environments (conda, venv, pyenv) and create kernel entries for them.
Unique: Integrates kernel discovery with VS Code's Python extension to auto-detect local environments (conda, venv, pyenv) and automatically create kernel entries, reducing manual configuration. Kernel selection is persistent per notebook file, stored in notebook metadata.
vs alternatives: More seamless environment switching than command-line Jupyter (no terminal context switching) and better integrated with VS Code's Python environment management than standalone JupyterLab, but lacks cloud provider integrations that some platforms offer.
Stores notebooks in the standard Jupyter .ipynb format (JSON with cells, metadata, outputs, and kernel info). The extension reads and writes .ipynb files directly, preserving cell order, execution counts, and output MIME bundles. Notebooks are version-controllable via Git; the extension provides no special merge conflict resolution, so conflicts must be resolved manually or with external tools. Cell metadata (tags, slide show settings) is preserved in the .ipynb JSON structure.
Unique: Uses the standard Jupyter .ipynb format without custom extensions, ensuring compatibility with other Jupyter tools and version control systems. Stores execution counts and output state in the file, enabling reproducibility but creating merge conflicts in collaborative scenarios.
vs alternatives: Fully compatible with standard Jupyter ecosystem and Git workflows, but less merge-friendly than some alternatives (e.g., Jupytext's percent-script format) and requires external tools for conflict resolution.
