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

Deadbolt has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and no email security records.

Launched on Product Hunt on August 22, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 1 day before launch. Our crawler found 9 technologies on this site, covering security, CDN, directory, and DNS providers. The stack includes Apple App Store, Cloudflare, and Cloudflare Bot Management.

It's also on one of the most common stacks we track, shared by 3,902 launches.
