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

Pterocos is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on April 28, 2026. The site is served through Cloudflare. Our crawler found 11 technologies on this site, covering CDN, CMS, DNS providers, and business email. The stack includes WordPress, CanvasJS, and Cloudflare.

It's also on one of the most common stacks we track, shared by 1,186 launches.
