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 6 June 2026; the live site may have changed since.
Virtual Piano has the basics covered well, with complete legal pages, a thorough launch checklist, and fast page loads. What needs work: missing several security headers and incomplete email security.
Launched on Product Hunt on June 6, 2026. The site is hosted on Cloudflare in the United States. Our crawler found 12 technologies on this site, covering advertising, analytics, CDN, and consent tooling. The stack includes Astro, Google Funding Choices, and Tailwind CSS.
Notably, it's running the same core stack as 206 other launches.
