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

PostgreSQL Academy has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, tracking cookies set before any opt-in, and no email security records.

Launched on PeerPush on July 1, 2026. The site is served through Cloudflare, with a domain registered 3 months before launch. Our crawler found 11 technologies on this site, covering analytics, CDN, chat widgets, and DNS providers. The stack includes Next.js, React, and Cloudflare.

It's also on one of the most common stacks we track, shared by 614 launches.
