Own this Launch?

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

EmailRSVP is largely in shape, with complete legal pages, well-configured email security, and clean crawl signals. Worth fixing first: missing several security headers.

Launched on Product Hunt on June 15, 2026. The domain was registered 4 months before launch. The crawl picked up 9 technologies on this site, covering frameworks, hosting, baas, and DNS providers. The stack includes Angular, Express, and Cloudflare DNS.

For context, it's on a stack we've seen on only 3 launches.
