FlowCastle
Build Telegram bots visually for simple automations, AI assistants, payments, support, and business workflows. Start without code, then add HTTP or TypeScript when you need more control.
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 2 July 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.
FlowCastle ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on July 2, 2026. The site is hosted on Hetzner Online GmbH in Germany, with a domain registered 4 months before launch. The crawl picked up 10 technologies on this site, covering analytics, DNS providers, email marketing, and web fonts. The stack includes Cloudflare DNS, Google Analytics, and Google Fonts.
