How these numbers are calculated

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