Preliminary
Editorial score out of 10. Not a benchmark.
What we tried
Asked for a dark settings panel in React and read the code it returned. We did not measure how often the first result is usable.
Scores are preliminary editorial notes from a short hands-on pass. They are not benchmark results, not pass rates, and not for sale. A shared task suite is not published yet, so we do not print speed, cost, or success-rate figures.

Good fit
- Starting a React or Next.js screen from a description
- Iterating on layout before it lives in a large repo
Limits
- Weaker fit for an existing non-React codebase
- Generated UI still needs a human pass on copy, states, and accessibility
