Microsoft Application Insights doesn't clearly lead Tailwind CSS in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose Tailwind CSS when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 18 audited Microsoft Application Insights sites and 1316 audited Tailwind CSS 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.
