Scalable reversi

scalable reversi: the (4+2n)**2grids reversi. infinite undo available via a1 style.

Added June 21, 2026 · Last analysed June 21, 2026 · via Hacker News

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 21 June 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.

Scalable reversi looks production-ready overall. Main gaps: missing Permissions-Policy and Strict-Transport-Security, incomplete legal pages, and no robots.txt.

Launched on Hacker News on June 21, 2026. The site is served through Cloudflare, with a domain registered 8 months before launch. We've detected 7 technologies on this site, covering advertising, CDN, DNS providers, and business email. The stack includes Brave Rewards, Cloudflare, and Cloudflare DNS.

It's more locked down than the typical Hacker News launch.
