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

Tabby covers some of the launch checklist, with complete legal pages and a thorough launch checklist. Visible gaps: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on August 24, 2026. The site is hosted on GitHub Pages and served through Fastly. Our crawler found 5 technologies on this site, covering CDN, developer tools, hosting, and javascript library. The stack includes Fastly, GitHub Pages, and HSTS.

It's also on one of the most common stacks we track, shared by 2,452 launches.

This score is based on structural patterns and is not definitive. Many legitimate sites may trigger signals, and AI-built sites may go undetected. It should be treated as an indicator, not a verdict.
