StackScope records what new websites are built with, the week they launch. Most we find ourselves, by watching public internet infrastructure for brand-new sites; the rest come from Product Hunt, Hacker News and PeerPush. We crawled this one for its tech stack and scored it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 14 July 2026; the live site may have changed since.
Every technology below links to its own page: which other new sites launched with it. Vendors and agencies watch those pages with Stackdar and hear about new adopters the week they ship, from £15 a month.
Upstream.so scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Permissions-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on July 14, 2026. The site is served through Cloudflare, with a domain registered in 2022. The crawl picked up 16 technologies on this site, covering advertising, analytics, CDN, and chat widgets. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's on one of the most common stacks we track, shared by 7,712 launches and more locked down than the typical Product Hunt launch.
