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

ToolsFree.ai scores highly overall, with complete legal pages, a thorough launch checklist, and clean crawl signals. Visible gaps: missing several security headers and incomplete email security.

Launched on PeerPush on April 28, 2026. The site is hosted on Railway, with a domain registered 9 weeks before launch. Our crawler found 17 technologies on this site, covering advertising, AI builders, analytics, and backend framework. The stack includes Google Funding Choices, Tailwind CSS, and Brevo.

It's also on one of the most common stacks we track, shared by 270 launches.
