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

Sous.bio has the basics covered well, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on August 9, 2026. The site is hosted on Railway, with a domain registered 5 months before launch. Our crawler found 10 technologies on this site, covering analytics, CSS frameworks, DNS providers, and business email. The stack includes Svelte, SvelteKit, and Tailwind CSS.

It's also one of just 5 launches we've crawled on this exact stack.
