Show HN: Stackzero - The Smarter Way to Discover Free Developer Tools

stackzero.revoseek.com · Added June 26, 2026 · Last analysed June 26, 2026 · via Hacker News · 62% unique tagline

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

Stackzero still has work before launch. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 26, 2026. The site is hosted on Amazon.com in the United States, with a domain registered in 2011. The crawl picked up 8 technologies on this site, covering package cdn, CSS frameworks, web fonts, and hosting. The stack includes Tailwind CSS, cdnjs, and Chart.js.

For context, it's on one of the most common stacks we track, shared by 2,086 launches.
