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

DeckWeaver covers some of the launch checklist, with fast page loads. What needs work: 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. Our crawler found 7 technologies on this site, covering backend framework, CDN, DNS providers, and frameworks. The stack includes htmx, Cloudflare, and Cloudflare DNS.

It's also on a stack we've seen on only 18 launches.
