Added June 29, 2026 · Last analysed June 29, 2026 · via · 62% unique tagline

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 June 2026; the live site may have changed since.

Danube Messaging is missing several launch fundamentals. What needs work: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Product Hunt on June 29, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. Our crawler found 7 technologies on this site, covering CDN, developer tools, DNS providers, and documentation. The stack includes Astro, Svelte, and Cloudflare.

It's also on a stack we've seen on only 4 launches.
