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 1 July 2026; the live site may have changed since.

Sendr is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on July 1, 2026. The site is hosted on Google LLC in the United States, with a domain registered 3 months before launch. The crawl picked up 12 technologies on this site, covering javascript library, baas, CSS frameworks, and developer tools. The stack includes Tailwind CSS, Firebase, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 5,298 launches.
