Choose GOV.UK Frontend when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
Ruby on Rails doesn't clearly lead GOV.UK Frontend in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Scores are medians across 13 audited GOV.UK Frontend sites and 62 audited Ruby on Rails sites in the BeaverCheck database. Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.
