If you work in the world of data engineering, you are probably familiar with Apache Arrow — the universal columnar format and multi-language toolbox that has become the gold standard for fast in-memory analytics and data interchange.

Notebook.link combines WebAssembly and the conda ecosystem to deliver scalable, serverless computing environments that run entirely in the browser.

By rewriting the SIMD optimizations of a critical low-level algorithm in Arrow C++, we have been able to deliver substantial speedups when reading Parquet data, up to 60% on some Arrow benchmarks with specific column encodings.

We introduce two new JupyterGIS features: a STAC browser integrated directly into JupyterGIS, and a new Story Map feature, which makes it possible to combine maps and narrative content in a single, interactive view.

We are thrilled to announce that JupyterLite is now an official part of Project Jupyter. This milestone marks a significant step forward for interactive computing in the browser and strengthens JupyterLite’s role within the Jupyter ecosystem.

Arbalister is a JupyterLab extension that enables seamless viewing of many tabular file formats, including Parquet, CSV, Avro, ORC, and SQLite.

We are excited to unveil notebook.link, a groundbreaking platform that simplifies sharing and running notebooks like never before.

The new 0.7 release includes a number of new features, bug fixes, and enhancements. This release also brings significant improvements to the user experience and new customization options for JupyterLite deployments.

QuantStack, an “almost accidental startup,” is building a serverless distro of JupyterLab for Jupyter’s global adoption.

JupyterLab 4.5 has been released! This new minor release of JupyterLab includes 51 new features and enhancements, 81 bug fixes, 44 maintenance tasks and 38 documentation improvements.

We are thrilled to announce the newest member of our JupyterLite kernel ecosystem: Xeus-Octave. Xeus-Octave allows you to run GNU Octave code directly on your browser.

Launched in June 2024, JupyterGIS was introduced as a collaborative, web-based GIS environment built on the JupyterLab framework. Its objective is to bring QGIS-inspired workflows into the browser…

We are thrilled to announce that the Sovereign Tech Fund is providing critical funding to sustain and improve Apache Arrow, an essential open-source project in the modern data ecosystem.

In today’s article, we had the chance to speak with Sylvain Corlay, long-time contributor of the Jupyter project, used by millions of people worldwide, and CEO-founder of QuantStack, an open-source development company employing around thirty people.

Since November 2024, QuantStack has been involved in the maintenance and development of Apache Arrow. We have a team of several engineers working…

JupyterGIS-tiler is a JupyterGIS extension that lets you use a notebook to process your (Xarray) data and make it available as raster tiles, so that it can be visualized in JupyterGIS.

Scientists and engineers utilize programming languages not only to build software systems but also to drive interactive exploratory workflows. They leverage developer tools to explore and reason through problems effectively.

The new 0.6.0 release includes a number of new features, bug fixes, and enhancements. This release also brings significant improvements to the user experience and new customization options for JupyterLite deployments.

JupyterLab 4.4 has been released! This new minor release of JupyterLab includes 28 new features and enhancements, 76 bug fixes, 63 maintenance tasks and 34 documentation improvements.

We are proud to announce the recipients of the Jupyter Distinguished Contributor (JDC) award for the 2024 cohort of contributors.
