Theme benchmarks
Every theme in the directory, measured under the same documented test configuration: Lighthouse, axe, and Core Web Vitals, run repeatedly and reported as a median you can reproduce.
Coming soon
The cross-theme benchmark table is being assembled run by run. In the meantime, each theme entry publishes its own performance and accessibility scores, the interactive benchmark viewer will let you query the full dataset, and the methodology page documents exactly how each number is produced.
