Onisin OS

Natural language meets your domain — locally

Added May 27, 2026 · Last analysed May 27, 2026 · via

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 27 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.

Onisin OS is early-stage. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on May 27, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 7 months before launch. We've detected 7 technologies on this site, covering CDN, developer tools, DNS providers, and email forwarding. The stack includes Fastly, GitHub Pages, and Google Domains DNS.

It's running the same core stack as 2,678 other launches.

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.
