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 27 April 2026; the live site may have changed since.

Offbook covers some of the launch checklist, with a thorough launch checklist and fast page loads. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 27, 2026. The site is served through Cloudflare, with a domain registered 4 days before launch. Our crawler found 5 technologies on this site, covering analytics, CDN, DNS providers, and meta-frameworks. The stack includes Astro, Cloudflare, and Cloudflare DNS.

It's also on one of the most common stacks we track, shared by 274 launches.
