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 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.
Filestay — Free File Tools That Never Upload Your Files ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: incomplete email security.
The site is served through Cloudflare, with a domain registered 2 days before launch. The crawl picked up 15 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Astro, Google Funding Choices, and Cloudflare.
For context, it's running the same core stack as 574 other launches and tighter on security headers than most StackScope Discovery 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.
