Show HN: ThreeFour – run multi-step procedures one step at a time

Added May 18, 2026 · Last analysed May 18, 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 18 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.

ThreeFour is partway there, with complete legal pages and well-configured email security. Main gaps: missing several security headers and no sitemap.

Launched on Hacker News on May 18, 2026. The site is served through Cloudflare, with a domain registered 11 weeks before launch. The crawl picked up 6 technologies on this site, covering CDN, developer tools, DNS providers, and email forwarding. The stack includes Vue.js, Cloudflare, and Cloudflare DNS.

For context, it's on one of the most common stacks we track, shared by 354 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.
