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 23 June 2026; the live site may have changed since.

DHTMLX Gantt Community Edition is largely in shape, with complete legal pages and clean crawl signals. Main gaps: missing several security headers, tracking cookies set before any opt-in, and incomplete email security.

Launched on Product Hunt on June 23, 2026. The site is hosted on DigitalOcean in the United States, with a domain registered in 2007. The crawl picked up 22 technologies on this site, covering javascript library, analytics, transactional email, and package cdn. The stack includes clipboard.js, DigitalOcean DNS, and DreamHost.

For context, it's one of only 47 launches we've crawled running DreamHost.
