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 12 June 2026; the live site may have changed since.

Masthead has the basics covered well, with a thorough launch checklist and clean crawl signals. What needs work: no Permissions-Policy, incomplete legal pages, and no email security records.

Launched on Hacker News on June 12, 2026. The site is hosted on Fly.io in the United States. Our crawler found 5 technologies on this site, covering DNS providers, transactional email, frameworks, and hosting. The stack includes Angular, Fly.io, and HSTS.

Notably, it's running a stack combination we've seen on no other launch and tighter on security headers than most Hacker News launches.
