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 7 July 2026; the live site may have changed since.

Reins ships with the basics, with a thorough launch checklist and fast page loads. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on July 7, 2026. The site is served through Cloudflare, with a domain registered in 2024. We've detected 9 technologies on this site, covering web fonts, ui library, CDN, and CSS frameworks. The stack includes Tailwind CSS, TanStack Start, and Cloudflare.

It's running the same core stack as 215 other launches.
