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

Performative-UI is missing several launch fundamentals. Worth fixing first: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.

Launched on Hacker News on June 8, 2026. The site is hosted on Fastly in the United States. Our crawler found 4 technologies on this site, covering build tooling, CDN, web fonts, and hosting. The stack includes Vite, Fastly, and GitHub Pages.

Notably, it's one of 62 launches on this exact stack.
