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 11 April 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.
PostSmith is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Main gaps: missing several security headers and tracking cookies set before any opt-in.
Launched on Product Hunt on April 9, 2026. The site is served through Cloudflare. The crawl picked up 14 technologies on this site, covering business email, security, analytics, and auth. The stack includes Clerk, Tailwind CSS, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 7,751 launches.
