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