How these numbers are calculated

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