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 2 September 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.
Featherline — Professional Color Grader is partway there, with complete legal pages and fast page loads. Worth fixing first: missing several security headers, no robots.txt or sitemap, and no email security records.
Launched on Product Hunt on September 2, 2026. The site is served through Cloudflare. The crawl picked up 7 technologies on this site, covering baas, CDN, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.
For context, it's running the same core stack as 7,672 other launches.
