Screenshot of Never miss a client deadline again

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 25 August 2026; the live site may have changed since.

Never miss a client deadline again looks production-ready overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing several security headers and incomplete email security.

Launched on Product Hunt on August 25, 2026. The site is hosted on netcup-AS - netcup GmbH in Germany, with a domain registered 1 week before launch. We've detected 3 technologies on this site, covering servers and DNS providers. The stack includes netcup DNS, nginx, and PHP.
