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 29 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.

AddEvent is largely in shape, with complete legal pages, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and tracking cookies set before any opt-in.

Launched on PeerPush on May 29, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2005. The crawl picked up 11 technologies on this site, covering affiliate, analytics, DNS providers, and business email. The stack includes Amplitude, Apache, and Atlassian.
