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 12 April 2026; the live site may have changed since.

LinearOS — The Browser Operating System still has work before launch. Worth fixing first: missing several security headers, incomplete legal pages, and no mobile viewport meta tag.

Launched on Product Hunt on April 12, 2026. The site is hosted on Vercel. The crawl picked up 3 technologies on this site, covering chat widgets, hosting, and security. The stack includes HSTS, SiteSpeak AI, and Vercel.

For context, it's running the same core stack as 2,971 other launches.
