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 1 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.

Robotomail scores highly overall, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: no Content-Security-Policy.

Launched on Product Hunt on May 1, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 7 weeks before launch. The crawl picked up 15 technologies on this site, covering analytics, advertising, CDN, and CSS frameworks. The stack includes Next.js, React, and Tailwind CSS.

For context, it's on one of the most common stacks we track, shared by 594 launches and more locked down than the typical Product Hunt launch.
