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 22 August 2026; the live site may have changed since.

OmniCalc ships with the basics, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and incomplete email security.

Launched on Product Hunt on August 22, 2026. The site is hosted on Netlify, with a domain registered 6 days before launch. We've detected 12 technologies on this site, covering affiliate, AI builders, analytics, and CSS frameworks. The stack includes Tailwind CSS, Bolt, and GoDaddy DNS.

It's on one of the most common stacks we track, shared by 823 launches.
