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 August 2026; the live site may have changed since.

SolarCalc24 — Free Solar Calculator has the basics covered well, with a complete set of security headers, a thorough launch checklist, and clean crawl signals. What needs work: incomplete legal pages and no email security records.

Launched on Product Hunt on August 8, 2026. The site is hosted on Netlify, with a domain registered 2 weeks before launch. Our crawler found 10 technologies on this site, covering analytics, baas, DNS providers, and forms. The stack includes Next.js, React, and Firebase.

It's also one of 92 launches on this exact stack and tighter on security headers than most Product Hunt launches.
