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 August 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.

StemGrab — Free AI Stem Splitter: Vocals, Drums, Bass & Instrumental ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. What needs work: no Content-Security-Policy and no email security records.

The site is served through Cloudflare, with a domain registered 2 weeks before launch. Our crawler found 7 technologies on this site, covering advertising, CDN, DNS providers, and web fonts. The stack includes Cloudflare, Cloudflare DNS, and Google AdSense.

It's also tighter on security headers than most StackScope Discovery launches.
