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

OpenBuilding is missing several launch fundamentals. Main gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on PeerPush on August 20, 2026. The site is hosted on Vercel. Our crawler found 7 technologies on this site, covering javascript library, CSS frameworks, developer tools, and hosting. The stack includes Tailwind CSS, HSTS, and Lucide Icons.

It's also on one of the most common stacks we track, shared by 3,045 launches.
