Own this Launch?

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 5 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.

PDFSign has the basics covered well, 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 Product Hunt on May 5, 2026. The site is served through Cloudflare, with a domain registered in 2017. Our crawler found 10 technologies on this site, covering seo, analytics, CDN, and DNS providers. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.

Readiness Breakdown How?

✓ Custom title and meta description

✓ Open Graph tags (title, image, description)

✓ Twitter card meta tags

✓ Canonical URL declared

✓ Responsive viewport meta tag

⚠

Page title is 88 characters (advisory) Google only shows about 60 characters of the title in search results; aim for 50–60 to keep the whole thing visible.

⚠

Meta description is 256 characters (advisory) Google only shows about 155–160 characters of the description in desktop search results (less on mobile); anything past that won't appear.
