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 29 April 2026; the live site may have changed since.
InvoiceAI scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: no Content-Security-Policy, tracking cookies set before any opt-in, and incomplete email security.
Launched on PeerPush on April 29, 2026. The site is served through Cloudflare. We've detected 15 technologies on this site, covering analytics, auth, baas, and CDN. The stack includes Auth.js, Next.js, and React.
It's on one of the most common stacks we track, shared by 3,880 launches and more locked down than the typical PeerPush launch.
