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

Financial, Medical & Scientific Tools 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 June 20, 2026. The site is hosted on Amazon.com in the United States. The crawl picked up 12 technologies on this site, covering advertising, consent tooling, CSS frameworks, and web fonts. The stack includes Google Funding Choices, Tailwind CSS, and Google Ads.

For context, it's running the same core stack as 496 other launches.
