Own this Launch?

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 4 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.

Option Profit Calculator ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on May 4, 2026. The site is served through Cloudflare, with a domain registered 2 weeks before launch. We've detected 6 technologies on this site, covering DNS providers, CDN, email forwarding, and protocol. The stack includes Cloudflare, Cloudflare DNS, and Google Search Console.
