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 20 June 2026; the live site may have changed since.
Mellum by JetBrains ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. What needs work: missing Permissions-Policy and Content-Security-Policy.
Launched on Product Hunt on June 20, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2001. The crawl picked up 27 technologies on this site, covering analytics, SaaS tooling, seo, and ai api. The stack includes Astro, CookieHub, and Airtable.
For context, it's running the same core stack as 134 other launches and tighter on security headers than most Product Hunt launches.
