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

DevToolBox looks production-ready overall, with a thorough launch checklist and clean crawl signals. Main gaps: missing several security headers, incomplete legal pages, and no email security records.

Launched on Hacker News on April 19, 2026. The site is hosted on The Constant Company in the United States. We've detected 14 technologies on this site, covering advertising, analytics, consent tooling, and CSS frameworks. The stack includes Google Funding Choices, Next.js, and React.

It's on one of the most common stacks we track, shared by 3,955 launches.
