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

Portero ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and fast page loads. Worth fixing first: missing several security headers and no email security records.

Launched on Product Hunt on July 14, 2026. The site is served through Cloudflare. We've detected 2 technologies on this site, covering CDN and DNS providers. The stack includes Cloudflare and Cloudflare DNS.
