Added August 7, 2026 · Last analysed August 7, 2026 · via Hacker News · also on StackScope Discovery

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 7 August 2026; the live site may have changed since.

Curio, a place for HTML files has the basics covered well, with a thorough launch checklist, well-configured email security, and clean crawl signals. Visible gaps: missing several security headers, incomplete legal pages, and tracking cookies set before any opt-in.

Launched on Hacker News on August 7, 2026. The site is hosted on Railway and served through Cloudflare, with a domain registered 6 days before launch. Our crawler found 11 technologies on this site, covering analytics, CDN, CSS frameworks, and DNS providers. The stack includes Next.js, React, and Tailwind CSS.

It's also on one of the most common stacks we track, shared by 502 launches.
