Highspeed Daemons of Performance
HOW GOOD IS YOUR
COMMERCE SCORE.
A free performance analyzer for online shops and web applications — specialized in e-commerce but works with any publicly accessible website. Analyzes frontends across 20+ metrics for mobile and desktop, including Core Web Vitals, TTFB, third-party script impact, and SEO score. The result: a weighted overall score plus a prioritized to-do list for development teams. Commerce Score is an open-source project by ScaleCommerce GmbH.
What is Commerce Score?
Commerce Score is a web-based analysis tool that measures and evaluates the frontend performance of online shops and web applications. Unlike generic tools such as Google Lighthouse, Commerce Score combines standardized measurement methods with its own e-commerce-proven checks. The tool was primarily developed for online shops – but since performance metrics are system-agnostic, it works equally well with CMS systems (WordPress, TYPO3, Drupal), corporate websites, headless frontends, and custom stacks. It analyzes multiple pages of the customer journey (homepage, category, product detail page) and delivers concrete action recommendations instead of raw measurement numbers.
