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 14 June 2026; the live site may have changed since.

PlanThat looks production-ready overall, with complete legal pages, a thorough launch checklist, and fast page loads. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on June 14, 2026. The site is hosted on Cloudflare in the United States, with a domain registered 6 months before launch. We've detected 12 technologies on this site, covering transactional email, CDN, cloud, and DNS providers. The stack includes Amazon SES, Amazon Web Services, and Ceph.

It's one of just 20 launches we've crawled on this exact stack.
