JupyterLab Distribution with a retro look and feel
RetroLab (also known as JupyterLab Retro, previously called JupyterLab Classic) is a JupyterLab distribution with a retro look and feel.
retrolab can be installed with
pip install retrolab
mamba install -c conda-forge retrolab
conda install -c conda-forge retrolab
retrolab can be started as a standalone app with:
Existing federated JupyterLab extensions listed via:

JupyterLab is the next-gen UI for Project Jupyter. Currently at version 3.0, it is becoming more mature and provides an advanced computational environment, that can sometimes be compared to what traditional IDEs offer.
However in some cases, having a leaner, simpler, and more focused interface to work on a notebook is really useful.
The single document mode as currently implemented in JupyterLab helps address this issue, but still displays a couple of visual cues that can be distracting to some users.
The goal of the
retrolab project is to provide an alternative JupyterLab distribution with the look and feed of the classic notebook UI, while leveraging the efforts put in the development of JupyterLab itself and its extension system.
retrolab reuses many of the existing plugins for JupyterLab (notebook, toolbar), and also supports prebuilt (federated) third-party extensions using the new distribution system added in 3.0. That way, extensions built for JupyterLab should also be compatible with
retrolab, as long as they can be added to the application shell provided by RetroLab.
Relation to other Jupyter frontends
RetroLab is an alternative frontend built using the latest JupyterLab components, with the look and feel of the Classic Jupyter Notebook UI. Below is a short comparison to know where it stands when compared to other Jupyter UI projects:
- Classic Jupyter Notebook - Classic frontend, classic notebook server.
- NBClassic - Classic frontend, new Jupyter Server.
- JupyterLab - Jupyterlab frontend, new Jupyter Server (or Classic Notebook Server). Extensions are not compatible with the Classic Jupyter Notebook since it is built with different components. With version 3.0 onwards, it uses the new Jupyter Server and supports federated extensions that don't need to be rebuilt on the end-user machine.
- RetroLab - JupyterLab frontend built with JupyterLab components, with the look and feel of the Classic Notebook. Consistent with the latest version of Jupyterlab. Extensions built for Jupyterlab should work as long as the components they depend on are part of this classic interface (for install RetroLab doesn't have the
This project is mostly a reboot of the two previous attempts at making something similar:
These projects really expressed the need for a stripped down, minimal version of the Jupyter Notebook UI.
retrolab contributes to that space with the added features:
- Support for existing federated (prebuilt) JupyterLab extensions
- Zen Mode
- Repo structure, similar to JupyterLab
- Reusing as much as possible from upstream JupyterLab
- Serve as a template and reference implementation for other alternative JupyterLab distributions
