Marimo: A Notebook that "Compiles" Python for Reproducibility and Reusability
summary
Marimo claims to “compile” Python notebooks by building a directed acyclic data‑flow graph from cell-level definitions and references, and actually implements that with Python’s ast module to power a reactive runtime that runs dependent cells, supports compiles cells to a DAG execution as scripts and web apps, and offers caching and module hot‑reloading. It enforces constraints (no cycles, no cross‑cell redefinition) because it uses static analysis only, and users report it works for reproducible, reusable notebooks.
