Own this Launch?

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 18 July 2026; the live site may have changed since.

PromptOptimizer is largely in shape, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 18, 2026. The site is served through Fastly, with a domain registered in 2023. The crawl picked up 8 technologies on this site, covering analytics, baas, CDN, and web fonts. The stack includes Angular, Fastly, and Firebase.

For context, it's on one of the most common stacks we track, shared by 119 launches.
