Reviewer scorecard
“Reactive execution eliminates the biggest Jupyter pain point — hidden state. Cells re-run when dependencies change.”
“Jest-compatible API with Vite's speed. ESM and TypeScript work without configuration. The watch mode is instant.”
“Finally, a Python notebook that doesn't produce unreproducible results. The reactive model is correct.”
“If you're using Vite, Vitest is the obvious choice. Even without Vite, the speed improvement over Jest is significant.”
“Marimo proves that notebooks can be reproducible. The deployment as web apps extends their utility.”
“Vitest is replacing Jest as the default test runner. Speed and modern JavaScript support drive the migration.”
