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.

InvoiceKaro is partway there, with complete legal pages. What needs work: missing several security headers, no robots.txt or sitemap, and no email security records.

Launched on Product Hunt on April 10, 2026. The site is hosted on Vercel. The crawl picked up 4 technologies on this site, covering web fonts, hosting, package cdn, and security. The stack includes Google Fonts, HSTS, and jsDelivr.

For context, it's running the same core stack as 2,955 other launches.
