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 August 2026; the live site may have changed since.
Sendra looks production-ready overall, with complete legal pages and a thorough launch checklist. Worth fixing first: missing several security headers, no robots.txt or sitemap, and incomplete email security.
Launched on Product Hunt on August 27, 2026. The site is served through Cloudflare, with a domain registered 4 months before launch. We've detected 8 technologies on this site, covering security, CDN, DNS providers, and email forwarding. The stack includes Cloudflare, Cloudflare Bot Management, and Cloudflare DNS.
