Reviewer scorecard
“IBM acquisition slowed development. The auto-generation from REST to GraphQL was interesting but the market moved on.”
“Reactive execution eliminates the biggest Jupyter pain point — hidden state. Cells re-run when dependencies change.”
“GraphQL-as-a-service is a solution looking for a larger market. Most teams that want GraphQL can build it.”
“Finally, a Python notebook that doesn't produce unreproducible results. The reactive model is correct.”
“API composition will be important but AI-powered approaches may replace declarative GraphQL generation.”
“Marimo proves that notebooks can be reproducible. The deployment as web apps extends their utility.”
