CodeFolio: open-source executable JS notebook canvas that doubles as your docs
jasonkneen · x · 2026-09-26
Developer Jason Kneen released CodeFolio, an experimental MIT-licensed "coding notebook canvas." Each page is a notebook interleaving markdown cells with runnable JavaScript cells, laid out on a freeform canvas. A persistent kernel evaluates cells top to bottom, variables carry across cells with @-references, and rich outputs (HTML, tables, charts, three.js scenes) render inline. Finished notebooks can be shared as docs/blogs or imported into other notebooks. Rough but open-sourced on GitHub.
