Crackr AI
An AI interviewer that speaks, listens, and scores you. Practice real coding interviews with voice, live code editor, and instant scorecards.
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.
Crackr AI has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. Main gaps: missing several security headers and incomplete email security.
Launched on PeerPush on April 2, 2026. The site is hosted on Vercel and served through Cloudflare, with a domain registered 3 weeks before launch. Our crawler found 14 technologies on this site, covering security, analytics, auth, and CDN. The stack includes Clerk, Next.js, and React.
It's also on one of the most common stacks we track, shared by 10,662 launches.
