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

A1Lab is largely in shape, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.

Launched on Product Hunt on August 18, 2026. The site is served through Bunny CDN. The crawl picked up 9 technologies on this site, covering CDN, DNS providers, email forwarding, and web fonts. The stack includes Bunny CDN, Bunny Fonts, and cdnjs.
