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 12 April 2026; the live site may have changed since.

Propelr scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on PeerPush on April 5, 2026. The site is served through AWS CloudFront, with a domain registered 7 months before launch. Our crawler found 11 technologies on this site, covering CDN, cloud, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 3,885 launches.
