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 4 June 2026; the live site may have changed since.

GitHub README Banner Creator looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no sitemap, and no email security records.

Launched on Product Hunt on June 4, 2026. The site is hosted on Cloudflare in the United States. We've detected 6 technologies on this site, covering baas, CDN, CSS frameworks, and web fonts. The stack includes Astro, Tailwind CSS, and Cloudflare.

It's on one of the most common stacks we track, shared by 205 launches.
