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