Share a notebook as one file anyone can run.
Save a page as a single .html file: its text, code, outputs and charts. Whoever opens it can read it in any browser and run the cells, with nothing to install.
What the file contains
The page’s text, its code cells with their saved outputs and charts, and the code that runs them. Attached files can be included too (off by default; the dialog shows what they add, and warns above 50 MB), so cells that read sales.csv still find it.
Cells in a shared notebook have no network access. The language runtimes load from Vellum’s file host, pinned to the versions the notebook was made with, so a notebook shared today keeps running the same way.
Other ways out
Any page also exports as Markdown, HTML or a Jupyter notebook (.ipynb), prints to PDF, and everything exports as an Obsidian-compatible .zip or one full backup.
