JupyterLite is a web-based distribution of JupyterLab that runs entirely in the browser, leveraging WebAssembly builds of language kernels and interpreters.

In this talk, we introduce emscripten-forge, a conda-based software distribution tailored for WebAssembly and the web browser. Emscripten-forge empowers several JupyterLite kernels, including:

– **xeus-Python** for Python,
– **xeus-R** for R,
– **xeus-Octave** for GNU Octave.

These kernels cover some of the most popular languages in scientific computing.

Additionally, emscripten-forge includes builds for various terminal applications, utilized by the Cockle shell emulator to enable the JupyterLite terminal.

PyData is an educational program of NumFOCUS, a 501(c)3 non-profit organization in the United States. PyData provides a forum for the international community of users and developers of data analysis tools to share ideas and learn from each other. The global PyData network promotes discussion of best practices, new approaches, and emerging technologies for data management, processing, analytics, and visualization. PyData communities approach data science using many languages, including (but not limited to) Python, Julia, and R.

PyData conferences aim to be accessible and community-driven, with novice to advanced level presentations. PyData tutorials and talks bring attendees the latest project features along with cutting-edge use cases.
