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

Coast FI Calculator is largely in shape, with clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on July 13, 2026. The site is hosted on Hostinger, with a domain registered 1 day before launch. The crawl picked up 8 technologies on this site, covering CSS frameworks, DNS providers, web fonts, and hosting. The stack includes Tailwind CSS, Chart.js, and Google Fonts.

For context, it's on one of the most common stacks we track, shared by 533 launches.
