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

Terasu scores highly overall, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Main gaps: tracking cookies set before any opt-in and incomplete email security.

Launched on Product Hunt on July 17, 2026. The site is hosted on AWS ALB and served through AWS CloudFront. The crawl picked up 14 technologies on this site, covering ui library, analytics, auth, and CDN. The stack includes Auth.js, Next.js, and React.

For context, it's one of just 13 launches we've crawled on this exact stack and more locked down than the typical Product Hunt launch.
