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

TenderVault is largely in shape, with complete legal pages, a thorough launch checklist, and clean crawl signals. Main gaps: missing several security headers and incomplete email security.

Launched on Product Hunt on April 23, 2026. The site is hosted on Google Cloud. The crawl picked up 14 technologies on this site, covering business email, seo, AI builders, and auth. The stack includes Clerk, Tailwind CSS, and Bing Webmaster.

For context, it's on one of the most common stacks we track, shared by 599 launches.
