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 8 May 2026; the live site may have changed since.
Sendly ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and clean crawl signals. Worth fixing first: missing Permissions-Policy and Strict-Transport-Security, tracking cookies set before any opt-in, and incomplete email security.
Launched on Product Hunt on May 8, 2026. The site is served through Cloudflare, with a domain registered 7 months before launch. We've detected 16 technologies on this site, covering analytics, auth, captcha, and CDN. The stack includes Clerk, Tailwind CSS, and Cloudflare.
It's running the same core stack as 7,384 other launches and tighter on security headers than most Product Hunt launches.
