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

Smart Compress is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Product Hunt on August 8, 2026. The site is hosted on Vercel. Our crawler found 21 technologies on this site, covering advertising, javascript library, package cdn, and analytics. The stack includes cdnjs, DOMPurify, and Google Ads.

It's also running the same core stack as 3,523 other launches.
