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 16 July 2026; the live site may have changed since.
Word Sudoku — A word twist on Sudoku still has work before launch. What needs work: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on July 16, 2026. The site is hosted on Firebase Hosting and served through Fastly. The crawl picked up 4 technologies on this site, covering CDN, web fonts, hosting, and security. The stack includes Fastly, Firebase Hosting, and Google Fonts.
For context, it's running the same core stack as 105 other launches.
