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

Physics Fundamentals is partway there, with a thorough launch checklist and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on July 20, 2026. The site is served through Cloudflare. The crawl picked up 22 technologies on this site, covering social embeds, wordpress plugin, package cdn, and advertising. The stack includes WordPress, AddThis, and cdnjs.

For context, it's on one of the most common stacks we track, shared by 1,217 launches.
