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

Coplain ships with the launch fundamentals in place, with complete legal pages, a complete set of security headers, and a thorough launch checklist. Worth fixing first: tracking cookies set before any opt-in and incomplete email security.

Launched on Product Hunt on June 27, 2026. The site is hosted on Railway in the United States, with a domain registered 5 weeks before launch. The crawl picked up 19 technologies on this site, covering analytics, advertising, ai api, and baas. The stack includes Next.js, React, and Anthropic.

For context, it's one of 68 launches on this exact stack and tighter on security headers than most Product Hunt launches.
