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

CRC Land covers some of the launch checklist. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on August 26, 2026. The site is hosted on Render and served through Cloudflare. Our crawler found 9 technologies on this site, covering analytics, CDN, CSS frameworks, and frameworks. The stack includes Svelte, SvelteKit, and Tailwind CSS.

It's also running a stack combination we've seen on no other launch.
