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.
OneShotCal is partway there, with complete legal pages and well-configured email security. Main gaps: missing several security headers and no robots.txt.
Launched on Product Hunt on April 4, 2026. The site is hosted on Google Cloud, with a domain registered 9 weeks before launch. The crawl picked up 5 technologies on this site, covering backend framework, DNS providers, web fonts, and hosting. The stack includes Express, Google Cloud, and Google Domains DNS.
For context, it's on one of the most common stacks we track, shared by 211 launches.
