How these numbers are calculated

TechLeads scans public websites and detects OpenGSE from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is OpenGSE's website count divided by the website counts of all Web servers technologies we track; a site using two Web servers tools counts for both. Counts were last refreshed on October 9, 2026 and update daily.
