Measured results, not claims.
Fast should be something you feel. These scores show how specific pages on the Showcase Site measured on Google PageSpeed Insights — each page is tested on its own, not as one score for the whole site.
The homepage snapshot includes Performance alongside Accessibility, Best Practices, and SEO so the 95 Mobile Performance result is presented in context.

Note: Mobile testing uses more demanding conditions than desktop, so mobile scores can be lower. A 95 is an exceptionally strong mobile performance result. Slēk balances speed, visual quality, and simplicity. PageSpeed scores are page-specific and can vary between runs. In September 2026 testing, the homepage measured 95 for Mobile Performance and 100 for Desktop Performance, while all four tested Explore pages reached 100 for Mobile Performance.
