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

Calsy - Calendar Scheduling System App still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Product Hunt on August 6, 2026. The site is hosted on Vercel. The crawl picked up 6 technologies on this site, covering analytics, developer tools, hosting, and security. The stack includes Google Analytics, Google Tag Manager, and HSTS.

For context, it's running the same core stack as 3,473 other launches.
