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

100kb.in has the basics covered well, with complete legal pages and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on June 30, 2026. The site is hosted on Vercel, with a domain registered 5 days before launch. Our crawler found 11 technologies on this site, covering analytics, CSS frameworks, business email, and frameworks. The stack includes Next.js, React, and Tailwind CSS.

It's also running the same core stack as 8,975 other launches.
