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 12 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.

mathOS looks production-ready overall, with a thorough launch checklist and clean crawl signals. What needs work: missing Permissions-Policy and Content-Security-Policy, incomplete legal pages, and no email security records.

Launched on Product Hunt on May 12, 2026. The site is served through Fastly. We've detected 8 technologies on this site, covering baas, CDN, DNS providers, and web fonts. The stack includes Flutter, Fastly, and Firebase.

It's one of 79 launches on this exact stack and tighter on security headers than most Product Hunt launches.

SignalPoints
AI code-structure signals +5

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
