Reviewer scorecard
“Still the best API development environment. Postbot generating tests from your API schema saves hours. Collections shared across teams are essential.”
“Reactive execution eliminates the biggest Jupyter pain point — hidden state. Cells re-run when dependencies change.”
“It has gotten bloated over the years but the core functionality is unmatched. The AI features are genuinely useful, not just checkbox items.”
“Finally, a Python notebook that doesn't produce unreproducible results. The reactive model is correct.”
“In an era of AI agents that can call APIs directly, do we still need a GUI for API testing? The future might be AI testing APIs autonomously.”
“Marimo proves that notebooks can be reproducible. The deployment as web apps extends their utility.”
