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 5 May 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.
Open Finance Playground ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Permissions-Policy and incomplete email security.
Launched on Product Hunt on May 5, 2026. The site is hosted on AWS S3 and served through AWS CloudFront. We've detected 33 technologies on this site, covering security, advertising, analytics, and CDN. The stack includes Astro, Didomi, and Sanity.
It's running a stack combination we've seen on no other launch and tighter on security headers than most Product Hunt launches.
