Show HN: CADara – I made an open-source in-browser CAD

Added May 9, 2026 · Last analysed May 9, 2026 · via Hacker News

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 9 May 2026; the live site may have changed since.

CADara is early-stage. Worth fixing first: missing several security headers, incomplete legal pages, and no sitemap.

Launched on Hacker News on May 8, 2026. The site is served through Cloudflare, with a domain registered in 2024. We've detected 5 technologies on this site, covering CDN, CSS frameworks, developer tools, and DNS providers. The stack includes Tailwind CSS, Cloudflare, and Cloudflare DNS.

It's running the same core stack as 7,384 other launches.
