How these numbers are calculated

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