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 28 April 2026; the live site may have changed since.
birthdays.app scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: no Permissions-Policy and incomplete email security.
Launched on PeerPush on April 28, 2026. The site is served through Cloudflare, with a domain registered in 2018. The crawl picked up 18 technologies on this site, covering advertising, analytics, package cdn, and APIs. The stack includes Algolia, Bubble.io, and cdnjs.
For context, it's more locked down than the typical PeerPush launch.
