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

Topicsapp is partway there, with clean crawl signals. What needs work: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Hacker News on August 21, 2026. The site is hosted on Vercel, with a domain registered 3 months before launch. The crawl picked up 5 technologies on this site, covering DNS providers, transactional email, hosting, and meta-frameworks. The stack includes Expo, GoDaddy DNS, and HSTS.

For context, it's on a stack we've seen on only 22 launches.
