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 28 July 2026; the live site may have changed since.
PostOwl looks production-ready overall, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing several security headers.
Launched on Product Hunt on July 28, 2026. The site is served through Cloudflare. We've detected 18 technologies on this site, covering advertising, analytics, affiliate, and baas. The stack includes Google, Svelte, and SvelteKit.
