Open source alternatives to Jupyter

One project on starwire does the same job. Ranked by how much of what Jupyter does each one covers, read from its README and website. Ties go to the most active.

What Jupyter does

Run code cell by cell with live outputcore
Inline charts and tablescore
Markdown notes beside code
Kernels for Python and other languages
Share or export notebooks
Interactive widgets

Each dot in the table is one job, in this order. Square dots are core jobs and count double. Full means yes, half means partly. "See the evidence" under a project shows the line behind each one. Coverage is what a project documents, not how well it works or how hard it is to move to. How we score this
