CostGuard
CostGuard — track and visualise your AI + cloud spend across OpenAI, Anthropic, AWS and Google Cloud.
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 27 June 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.
CostGuard is partway there, with complete legal pages and fast page loads. Main gaps: missing several security headers, no robots.txt or sitemap, and tracking cookies set before any opt-in.
Launched on PeerPush on June 27, 2026. The site is hosted on Vercel, with a domain registered 7 weeks before launch. The crawl picked up 9 technologies on this site, covering analytics, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Google Fonts, and HSTS.
For context, it's on one of the most common stacks we track, shared by 3,371 launches.

| AI writing signals | +5 |
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.
