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.
Feistyduck is largely in shape, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing several security headers and no sitemap.
Launched on Hacker News on August 27, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered in 2006. The crawl picked up 13 technologies on this site, covering backend framework, DNS providers, business email, and transactional email. The stack includes Apache, AWS Route 53, and Bluesky.
