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 25 August 2026; the live site may have changed since.

folyn still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 25, 2026. The site is hosted on GitHub Pages and served through Fastly. The crawl picked up 4 technologies on this site, covering CDN, CSS frameworks, hosting, and ui library. The stack includes Tailwind CSS, Fastly, and GitHub Pages.

For context, it's running the same core stack as 290 other launches.
