Own this Launch?

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

Yes-Brainer ships with the basics, with a thorough launch checklist, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers and incomplete legal pages.

Launched on Hacker News on July 13, 2026. The site is hosted on GitHub Pages and served through Fastly, with a domain registered 6 weeks before launch. We've detected 6 technologies on this site, covering javascript library, CDN, developer tools, and DNS providers. The stack includes Fastly, GitHub Pages, and Google Domains DNS.

It's running the same core stack as 1,653 other launches.
