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

Compress Excel ships with the launch fundamentals in place, with complete legal pages and clean crawl signals. Worth fixing first: no Strict-Transport-Security and incomplete email security.

Launched on Product Hunt on April 13, 2026. The site is hosted on Hostinger and served through Cloudflare, with a domain registered 8 months before launch. Our crawler found 12 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Google Funding Choices, cdnjs, and Cloudflare.

It's also running the same core stack as 888 other launches and tighter on security headers than most Product Hunt launches.
