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