Fx

Show HN: Antimemetic message that escapes screen capture

Developer Tools

Added May 25, 2026 · Last analysed May 25, 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 25 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.

Fx is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on May 25, 2026. The site is hosted on Vercel, with a domain registered in 2010. We've detected 3 technologies on this site, covering hosting, meta-frameworks, and security. The stack includes SvelteKit, HSTS, and Vercel.

It's on a stack we've seen on only 14 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.
