Own this Launch?

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 12 May 2026; the live site may have changed since.

LeadSave ships with the launch fundamentals in place, with complete legal pages, a thorough launch checklist, and well-configured email security. Worth fixing first: missing Referrer-Policy and Permissions-Policy.

Launched on Product Hunt on May 12, 2026. The site is hosted on Google Cloud. We've detected 7 technologies on this site, covering hosting, auth, web fonts, and protocol. The stack includes Google Sign-In, Google Cloud, and Google Developer Site.

It's a rare Google Developer Site sighting, just 3 in our data and tighter on security headers than most Product Hunt launches.
