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