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 August 2026; the live site may have changed since.

Riffn has the basics covered well, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers.

Launched on Hacker News on August 15, 2026. The site is served through Cloudflare. Our crawler found 4 technologies on this site, covering CDN, DNS providers, business email, and SaaS tooling. The stack includes Cloudflare, Cloudflare DNS, and Zoho.
