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 11 August 2026; the live site may have changed since.
PromptTools is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and no email security records.
Launched on Product Hunt on August 11, 2026. The site is served through AWS CloudFront, with a domain registered 5 months before launch. The crawl picked up 14 technologies on this site, covering advertising, analytics, CDN, and cloud. The stack includes Google Funding Choices, Next.js, and React.
For context, it's on one of the most common stacks we track, shared by 4,856 launches.
