AI

Added August 23, 2026 · Last analysed August 31, 2026 · via StackScope Discovery · also on Product Hunt

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 31 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.

Rumix — Multiplayer AI for engineering teams ships with the basics, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. We've detected 10 technologies on this site, covering security, CDN, CSS frameworks, and directory. The stack includes Next.js, React, and Tailwind CSS.

It's on one of the most common stacks we track, shared by 14,981 launches.
