No menus. No distractions. Just endless, beautiful Sudoku. Open Gridfulness and start playing instantly.
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 30 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.
Gridfulness — Pure, Minimalist Sudoku still has work before launch. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
The site is served through Fastly, with a domain registered 3 weeks before launch. The crawl picked up 9 technologies on this site, covering analytics, baas, CDN, and CSS frameworks. The stack includes Astro, Tailwind CSS, and Fastly.
For context, it's on one of the most common stacks we track, shared by 840 launches.

Indicative grade from a single automated render, not a substitute for Lighthouse or field data, and not part of the StackScope score.

| AI code-structure signals | +20 |
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.
