Screenshot of Defend

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 21 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.

Defend is early-stage. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on April 21, 2026. The site is hosted on GoDaddy, with a domain registered 4 weeks before launch. We've detected 3 technologies on this site, covering advertising, DNS providers, and hosting. The stack includes GoDaddy, GoDaddy DNS, and Google AdSense.

It's one of 75 launches on this exact stack.
