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 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.

Sentinelle is largely in shape, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: no robots.txt or sitemap.

Launched on Product Hunt on May 21, 2026. The site is hosted on Vercel. The crawl picked up 9 technologies on this site, covering baas, captcha, CSS frameworks, and error tracking. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 14,981 launches and more locked down than the typical Product Hunt launch.
