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 12 June 2026; the live site may have changed since.
Qursor ships with the basics, with a thorough launch checklist. What needs work: missing several security headers, incomplete legal pages, and no sitemap.
Launched on Product Hunt on June 12, 2026. The site is hosted on Cloudflare in the United States. We've detected 14 technologies on this site, covering web fonts, seo, analytics, and auth. The stack includes Astro, Clerk, and Tailwind CSS.
It's running the same core stack as 239 other launches.
