Screenshot of Percenty

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 April 2026; the live site may have changed since.

Percenty has the basics covered well, with complete legal pages, well-configured email security, and clean crawl signals. What needs work: missing several security headers.

Launched on Product Hunt on April 23, 2026. The site is hosted on Netlify. Our crawler found 11 technologies on this site, covering advertising, business email, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Tailwind CSS, and GoDaddy DNS.

It's also running the same core stack as 640 other launches.
