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 17 June 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.

T-SQL Online scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing Permissions-Policy and Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 17, 2026. The site is served through Cloudflare. We've detected 14 technologies on this site, covering analytics, advertising, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Web Analytics.

It's more locked down than the typical Product Hunt launch.
