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

Inbox is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and no email security records.

Launched on Hacker News on April 1, 2026. The site is served through AWS CloudFront, with a domain registered 5 months before launch. The crawl picked up 10 technologies on this site, covering cloud, CDN, CSS frameworks, and DNS providers. The stack includes htmx, Tailwind CSS, and Amazon Web Services.

For context, it's on a stack we've seen on only 23 launches.
