The New Stack Makers

JupyterLite, a fully browser-based distribution of JupyterLab, is enabling new levels of global scalability in technical education. Developed by Sylvain Corlay’s QuantStack team, it allows math and programming lessons to run entirely in students’ browsers — kernel included — without relying on Docker or cloud-scale infrastructure. Its most prominent success is Capytale, a French national deployment that supports half a million high school students and over 200,000 weekly sessions from essentially a single server, which hosts only teaching content while computation happens locally in each browser.QuantStack, founded in 2016 as what Corlay calls an “accidental startup,” has since grown into a 30-person team contributing across Jupyter, Conda-Forge, and Apache Arrow. But JupyterLite embodies its most ambitious goal: making programming education accessible to countries with rapidly growing youth populations, such as Nigeria, where traditional cloud-hosted notebooks are impractical.
