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 13 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.

InkSeal is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on May 13, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 12 weeks before launch. The crawl picked up 4 technologies on this site, covering CDN, cloud, DNS providers, and hosting. The stack includes Amazon Web Services, AWS CloudFront, and AWS Route 53.

For context, it's on one of the most common stacks we track, shared by 513 launches.
