Criboku — a daily cribbage puzzle
A daily cribbage puzzle. Fill in the missing cards so every row, column and corner square scores exactly what it says. One solution, never a guess, and a new puzzle every day.
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 20 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.
Criboku — a daily cribbage puzzle has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.
The site is hosted on MartNet, with a domain registered 6 days before launch. Our crawler found 5 technologies on this site, covering analytics, DNS providers, business email, and hosting. The stack includes Fastmail, GoatCounter, and HSTS.

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.
