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 July 2026; the live site may have changed since.
ApexCalculators scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and no email security records.
Launched on Product Hunt on July 8, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 10 weeks before launch. The crawl picked up 16 technologies on this site, covering advertising, CDN, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Tailwind CSS, and Cloudflare.
For context, it's on one of the most common stacks we track, shared by 516 launches.
