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