Csrct

How bottlenecks reveal the hidden architecture of technological power

Developer Tools

Added May 1, 2026 · Last analysed May 1, 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 1 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.

Csrct has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Visible gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.

Launched on Hacker News on May 1, 2026. The site is served through Cloudflare, with a domain registered in 2010. Our crawler found 12 technologies on this site, covering security, analytics, backend framework, and CDN. The stack includes Amazon Web Services, Cloudflare, and Cloudflare Bot Management.
