Own this Launch?

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

Vent-off is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt.

Launched on Product Hunt on April 5, 2026. The site is hosted on IONOS, with a domain registered 5 days before launch. Our crawler found 8 technologies on this site, covering hosting, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Google Search Console, and HSTS.

It's also one of 30 launches on this exact stack.
