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 22 April 2026; the live site may have changed since.

ZumaPiano has the basics covered well, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 22, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered in 2023. Our crawler found 7 technologies on this site, covering CDN, cloud, DNS providers, and transactional email. The stack includes Amazon Web Services, AWS CloudFront, and AWS S3.

It's also on one of the most common stacks we track, shared by 343 launches.
