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

AI Leetcode Coach is partway there, with a thorough launch checklist and clean crawl signals. Worth fixing first: missing several security headers, incomplete legal pages, and no email security records.

Launched on Product Hunt on April 14, 2026. The site is hosted on Vercel. The crawl picked up 7 technologies on this site, covering advertising, web fonts, hosting, and javascript library. The stack includes cdnjs, Google Fonts, and Google Search Console.

For context, it's running the same core stack as 2,959 other launches.
