TechLeads scans public websites and detects Tailwind CSS from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Tailwind CSS's website count divided by the website counts of all UI frameworks technologies we track; a site using two UI frameworks tools counts for both. Counts were last refreshed on October 8, 2026 and update daily.
