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 27 August 2026; the live site may have changed since.
Papiano scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Visible gaps: incomplete email security.
Launched on Product Hunt on August 27, 2026. The site is hosted on AWS S3 and served through AWS CloudFront, with a domain registered 8 weeks before launch. The crawl picked up 10 technologies on this site, covering captcha, CDN, cloud, and DNS providers. The stack includes Amazon Web Services, AWS CloudFront, and AWS S3.
For context, it's on one of the most common stacks we track, shared by 487 launches and more locked down than the typical Product Hunt launch.
