<a href="https://techleads.fyi/technology/extjs/market-share">ExtJS market share (TechLeads data)</a>Websites using each technology in the TechLeads index, and its share of all JavaScript frameworks detections.
In HTTP Archive's monthly crawl of public websites, ExtJS was detected on 12,597 pages in September 2026, down 12.8% from a year earlier (peak: 24,381). HTTP Archive is a separate dataset from the TechLeads index, so its numbers are not added to ours.
Same month, other JavaScript Frameworks technologies in HTTP Archive: React 7,210,181, GSAP 4,697,200, Vue.js 2,655,312, Next.js 2,090,368, Next.js App Router 1,514,274.
Based on country-code domains (such as .de or .co.uk); websites on .com and other generic domains are not assigned a country.

TechLeads scans public websites and detects ExtJS from signals in the page HTML, scripts, cookies, HTTP headers and DNS records. Market share is ExtJS'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 9, 2026 and update daily.
