Does that now include the ability to create and edit, or still just run? Having to rely on a third party to create and edit could be problematic for some purposes.

A comment from May last year [1] says "But that won’t include the editable notebook interface or the rest of observablehq.com - unlike Jupyter, we’re really aiming to create a community and cross-pollination of concepts and code rather than individual installations. We might eventually launch something that enables offline editing, but that’s a bit further out in the future."
