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 20 June 2026; the live site may have changed since.
Kalendra is missing several launch fundamentals. Visible gaps: missing several security headers, incomplete legal pages, and no robots.txt or sitemap.
Launched on Product Hunt on June 20, 2026. The site is hosted on Amazon.com in the United States, with a domain registered 7 months before launch. Our crawler found 8 technologies on this site, covering transactional email, developer tools, DNS providers, and web fonts. The stack includes Amazon SES, GoDaddy DNS, and Google Fonts.
Notably, it's on one of the most common stacks we track, shared by 1,171 launches.
