StackScope is a free public catalogue of indie launches. We find launches on Product Hunt, Hacker News and similar feeds, then crawl each site to detect its tech stack and score it for launch readiness: DNS, security headers, SEO basics. This page is what we saw on 22 April 2026; the live site may have changed since.
Notation is partway there, with a thorough launch checklist and fast page loads. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Hacker News on April 22, 2026. The site is served through Cloudflare, with a domain registered 1 week before launch. The crawl picked up 8 technologies on this site, covering CDN, CSS frameworks, DNS providers, and email forwarding. The stack includes Astro, Tailwind CSS, and Apple App Store.
For context, it's on one of the most common stacks we track, shared by 469 launches.
