TechLeads scans public websites and detects Radix UI from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is Radix UI'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.
