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.
