How is Zasper better than JupyterLab ?
- Up to 5X Less CPU usage
- Up to 40X Less RAM usage
- Higher throughput
- Lower latency
- Highly resilient under very high loads
Benchmark comparision report can be accessed here.

Available kernels:
deno /Users/prasunanand/Library/Jupyter/kernels/deno
firstenv /Users/prasunanand/Library/Jupyter/kernels/firstenv
gonb /Users/prasunanand/Library/Jupyter/kernels/gonb
ir /Users/prasunanand/Library/Jupyter/kernels/ir

The simplest way to install a Python 3 Jupyter kernel is
pip install ipykernel
or
pip install jupyter
Create an environment.
conda create --name torchEnv
Activate the environment.
conda activate torchEnv
Install the necessary packages and ipykernel
conda install -c anaconda ipykernel
Create kernelspec file and you are done! 🚀
python -m ipykernel install --user --name=torchEnv
Create a project.
uv init exampleUV
cd exampleUV
uv run main.py # This creates a .venv directory
Activate the environment.
source .venv/bin/activate
Install the necessary packages and ipykernel
uv pip install ipykernel
Create kernelspec file and you are done! 🚀
uv run python -m ipykernel install --user --name=exampleUV
Download zasper from Github and initialize the dependencies.
git clone https://github.com/zasper-io/zasper
cd zasper
make init
make webapp-install
This will create a binary zasper and add it to your go executables directory. Make sure you have go executables on your path.
Run zasper in any directory to see if the installation was done correctly.
prasunanand@Prasuns-Laptop example % zasper --help
Usage of zasper:
-cwd string
base directory of project (default ".")
-debug
sets log level to debug
-port string
port to start the server on (default ":8048")
-protected
enable protected mode
make electron-package-mac # on macOS
make electron-package-linux # on Linux
This creates zasper-0.1.0-arm64.dmg(macOS) and zasper_0.1.0_arm64.deb(Debian) installer.

By default, the application writes logs to the following locations:
on Linux: ~/.config/zasper/logs/main.log
on macOS: ~/Library/Logs/zasper/main.log
on Windows: %USERPROFILE%\AppData\Roaming\zasper\logs\main.logData Scientists and AI Engineers spend most of their time running Notebooks on IDEs and hence need a robust ecosystem. Zasper aspires to be a full fledged IDE and the future development will be along making it more efficient by:
- Allowing custom data apps support rather than just Jupyter Notebooks.
- Easier integration with the existing tools.
- Zasper Hub for Self Hosted deployment in the cloud.

Zasper would not exist without the incredible work of the Jupyter community. Zasper uses the Jupyter wire protocol and draws inspiration from its architecture. Deep thanks to all Jupyter contributors for laying the groundwork. Data Science Notebooks would not have existed without them.
