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 13 August 2026; the live site may have changed since.

Postilo has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers, no sitemap, and no email security records.

Launched on Product Hunt on August 13, 2026. The site is served through Cloudflare, with a domain registered in 2023. Our crawler found 10 technologies on this site, covering ui library, AI builders, analytics, and CDN. The stack includes Tailwind CSS, Cloudflare, and HSTS.

It's also on one of the most common stacks we track, shared by 6,950 launches.
