Mission
This site was built to better inform Shopify merchants and theme developers about theme performance. The goals are:
- Provide theme developers with aggregated shop data so that they can understand how their theme is currently performing and which metrics need the most work.
- Provide merchants with aggregated theme data so that they can balance the tradeoffs between the features and performance of themes with their budget for custom theme development.
About the data
All of the data reported here is publicly available through HTTPArchive and the Chrome User Experience Report (CrUX) via BigQuery. Information about whether a website is on Shopify and which theme it uses comes from HTTPArchive. That data is then joined with CrUX to obtain real-user performance metrics from sessions in Chrome browsers. You can find and review the query in this site's source code.
