Promptex - Build Chrome Extensions with AI Chat
Describe your browser extension in natural language. Watch the AI generate files, test in a live preview environment, self-heal, and download a working Manifest V3 zip.
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 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.
Promptex - Build Chrome Extensions with AI Chat covers some of the launch checklist, with complete legal pages. Visible gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.
The site is hosted on Vercel. Our crawler found 12 technologies on this site, covering analytics, ui library, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.
