Screenshot of Markdown Viewer and Editor

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 1 September 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.

Markdown Viewer and Editor still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on August 31, 2026. The site is served through Cloudflare, with a domain registered 12 weeks before launch. The crawl picked up 8 technologies on this site, covering javascript library, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare DNS, and Cloudflare Email Routing.
